--*!
--*! Revision 1.9 2001/06/14 10:00:14 jonashg
--*! No need for tempudelay to be inline anymore (had to adjust the usec to
--*! loops conversion because of this to make it slow enough to be a udelay).
--*!
--*! Revision 1.8 2001/06/14 08:06:32 jonashg

--*! * Removed comment about /proc (nothing is exported there).
--*!
--*! Revision 1.5 2001/06/12 14:35:13 jonashg
--*! Gave the module a name and added it to printk's.
--*!
--*! Revision 1.4 2001/05/31 14:53:40 jonashg
--*! Made tempudelay() inline so that the watchdog doesn't reset (see
--*! function comment).
--*!
--*! Revision 1.3 2001/03/26 16:03:06 bjornw
--*! Needs linux/config.h
--*!
--*! Revision 1.2 2001/03/20 19:42:00 bjornw
--*! Use the ETRAX prefix on the DS1302 options
--*!

--*!
--*! Revision 1.8 2000/02/23 16:59:18 torbjore
--*! added setup of R_GEN_CONFIG when RTC is connected to the generic port.
--*!
--*! Revision 1.7 2000/01/17 15:51:43 johana
--*! Added RTC_SET_CHARGE ioctl to enable trickle charger.
--*!
--*! Revision 1.6 1999/10/27 13:19:47 bjornw
--*! Added update_xtime_from_cmos which reads back the updated RTC into the kernel.
--*! /dev/rtc calls it now.
--*!
--*! Revision 1.5 1999/10/27 12:39:37 bjornw
--*! Disabled superuser check. Anyone can now set the time.
--*!
--*! Revision 1.4 1999/09/02 13:27:46 pkj
--*! Added shadow for R_PORT_PB_CONFIG.
--*! Renamed port_g_shadow to port_g_data_shadow.
--*!
--*! Revision 1.3 1999/09/02 08:28:06 pkj
--*! Made it possible to select either port PB or the generic port for the RST
--*! signal line to the DS1302 RTC.
--*! Also make sure the RST bit is configured as output on Port PB (if used).
--*!
--*! Revision 1.2 1999/09/01 14:47:20 bjornw
--*! Added support for /dev/rtc operations with ioctl RD_TIME and SET_TIME to read
--*! and set the date. Register as major 121.
--*!

-- * Revision 1.3 2002/05/28 16:16:07 johana
-- * Handle empty fast_timer_list
-- *
-- * Revision 1.2 2002/05/27 15:38:42 johana
-- * Made it compile without warnings on Linux 2.4.
-- * (includes, wait_queue, PROC_FS and snprintf)
-- *
-- * Revision 1.1 2002/05/27 15:32:25 johana
-- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
-- *
-- * Revision 1.8 2001/11/27 13:50:40 pkj
-- * Disable interrupts while stopping the timer and while modifying the
-- * list of active timers in timer1_handler() as it may be interrupted
-- * by other interrupts (e.g., the serial interrupt) which may add fast
-- * timers.
-- *
-- * Revision 1.7 2001/11/22 11:50:32 pkj
-- * * Only store information about the last 16 timers.
-- * * proc_fasttimer_read() now uses an allocated buffer, since it
-- * requires more space than just a page even for only writing the
-- * last 16 timers. The buffer is only allocated on request, so
-- * unless /proc/fasttimer is read, it is never allocated.
-- * * Renamed fast_timer_started to fast_timers_started to match
-- * fast_timers_added and fast_timers_expired.
-- * * Some clean-up.
-- *
-- * Revision 1.6 2000/12/13 14:02:08 johana
-- * Removed volatile for fast_timer_list
-- *
-- * Revision 1.5 2000/12/13 13:55:35 johana
-- * Added DEBUG_LOG, added som cli() and cleanup
-- *
-- * Revision 1.4 2000/12/05 13:48:50 johana
-- * Added range check when writing proc file, modified timer int handling
-- *
-- * Revision 1.3 2000/11/23 10:10:20 johana
-- * More debug/logging possibilities.
-- * Moved GET_JIFFIES_USEC() to timex.h and time.c
-- *
-- * Revision 1.2 2000/11/01 13:41:04 johana
-- * Clean up and bugfixes.
-- * Created new do_gettimeofday_fast() that gets a timeval struct
-- * with time based on jiffies and *R_TIMER0_DATA, uses a table
-- * for fast conversion of timer value to microseconds.
-- * (Much faster the standard do_gettimeofday() and we don't really
-- * wan't to use the true time - we wan't the "uptime" so timers don't screw up
-- * when we change the time.
-- * TODO: Add efficient support for continuous timers as well.
-- *
-- * Revision 1.1 2000/10/26 15:49:16 johana
-- * Added fasttimer, highresolution timers.

-+ *
-+ * Changelog:
-+ * 01-31-2000 DMW Created
-+ * 09-18-2000 SJH Moved structure out of the Disk-On-Chip drivers
-+ * so it can be used by other NAND flash device
-+ * drivers. I also changed the copyright since none
-+ * of the original contents of this file are specific
-+ * to DoC devices. David can whack me with a baseball
-+ * bat later if I did something naughty.
-+ * 10-11-2000 SJH Added private NAND flash structure for driver
-+ * 10-24-2000 SJH Added prototype for 'nand_scan' function
-+ * 10-29-2001 TG changed nand_chip structure to support
-+ * hardwarespecific function for accessing control lines
-+ * 02-21-2002 TG added support for different read/write adress and
-+ * ready/busy line access function
-+ * 02-26-2002 TG added chip_delay to nand_chip structure to optimize
-+ * command delay times for different chips
-+ * 04-28-2002 TG OOB config defines moved from nand.c to avoid duplicate
-+ * defines in jffs2/wbuf.c
-+ * 08-07-2002 TG forced bad block location to byte 5 of OOB, even if
-+ * CONFIG_MTD_NAND_ECC_JFFS2 is not set
-+ * 08-10-2002 TG extensions to nand_chip structure to support HW-ECC
-+ *
-+ * 08-29-2002 tglx nand_chip structure: data_poi for selecting
-+ * internal / fs-driver buffer
-+ * support for 6byte/512byte hardware ECC
-+ * read_ecc, write_ecc extended for different oob-layout
-+ * oob layout selections: NAND_NONE_OOB, NAND_JFFS2_OOB,
-+ * NAND_YAFFS_OOB
-+ * 11-25-2002 tglx Added Manufacturer code FUJITSU, NATIONAL
-+ * Split manufacturer and device ID structures
-+ *
-+ * 02-08-2004 tglx added option field to nand structure for chip anomalities
-+ * 05-25-2004 tglx added bad block table support, ST-MICRO manufacturer id
-+ * update of nand_chip structure description
-+ * 01-17-2005 dmarlin added extended commands for AG-AND device and added option
-+ * for BBT_AUTO_REFRESH.
-+ * 01-20-2005 dmarlin added optional pointer to hardware specific callback for
-+ * extra error status checks.

-+ * Snitched from drivers/mtd/nand_base.c
-+ * Modified to run outside Linux.
-+ * #if 0'd to remove non-essential functionality
-+ *
-+ * Overview:
-+ * This is the generic MTD driver for NAND flash devices. It should be
-+ * capable of working with almost all NAND chips currently available.
-+ * Basic support for AG-AND chips is provided.
-+ *
-+ * Additional technical information is available on
-+ * http://www.linux-mtd.infradead.org/tech/nand.html
-+ *
-+ * Copyright (C) 2000 Steven J. Hill (sjhill@realitydiluted.com)
-+ * 2002 Thomas Gleixner (tglx@linutronix.de)
-+ *
-+ * 02-08-2004 tglx: support for strange chips, which cannot auto increment
-+ * pages on read / read_oob
-+ *
-+ * 03-17-2004 tglx: Check ready before auto increment check. Simon Bayes
-+ * pointed this out, as he marked an auto increment capable chip
-+ * as NOAUTOINCR in the board driver.
-+ * Make reads over block boundaries work too
-+ *
-+ * 04-14-2004 tglx: first working version for 2k page size chips
-+ *
-+ * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
-+ *
-+ * 09-24-2004 tglx: add support for hardware controllers (e.g. ECC) shared
-+ * among multiple independend devices. Suggestions and initial patch
-+ * from Ben Dooks <ben-mtd@fluff.org>
-+ *
-+ * 12-05-2004 dmarlin: add workaround for Renesas AG-AND chips "disturb" issue.
-+ * Basically, any block not rewritten may lose data when surrounding blocks
-+ * are rewritten many times. JFFS2 ensures this doesn't happen for blocks
-+ * it uses, but the Bad Block Table(s) may not be rewritten. To ensure they
-+ * do not lose data, force them to be rewritten when some of the surrounding
-+ * blocks are erased. Rather than tracking a specific nearby block (which
-+ * could itself go bad), use a page address 'mask' to select several blocks
-+ * in the same area, and rewrite the BBT when any of them are erased.
-+ *
-+ * 01-03-2005 dmarlin: added support for the device recovery command sequence for Renesas
-+ * AG-AND chips. If there was a sudden loss of power during an erase operation,
-+ * a "device recovery" operation must be performed when power is restored
-+ * to ensure correct operation.
-+ *
-+ * 01-20-2005 dmarlin: added support for optional hardware specific callback routine to
-+ * perform extra error status checks on erase and write failures. This required
-+ * adding a wrapper function for nand_read_ecc.
-+ *
-+ * 08-20-2005 vwool: suspend/resume added
-+ *
-+ * Credits:
-+ * David Woodhouse for adding multichip support
-+ *
-+ * Aleph One Ltd. and Toby Churchill Ltd. for supporting the
-+ * rework for 2K page size chips
-+ *
-+ * TODO:
-+ * Enable cached programming for 2k page size chips
-+ * Check, if mtd->ecctype should be set to MTD_ECC_HW
-+ * if we have HW ecc support.
-+ * The AG-AND chips have nice features for speed improvement,
-+ * which are not supported yet. Read / program 4 pages in one go.

-+ *
-+ * Description:
-+ *
-+ * When nand_scan_bbt is called, then it tries to find the bad block table
-+ * depending on the options in the bbt descriptor(s). If a bbt is found
-+ * then the contents are read and the memory based bbt is created. If a
-+ * mirrored bbt is selected then the mirror is searched too and the
-+ * versions are compared. If the mirror has a greater version number
-+ * than the mirror bbt is used to build the memory based bbt.
-+ * If the tables are not versioned, then we "or" the bad block information.
-+ * If one of the bbt's is out of date or does not exist it is (re)created.
-+ * If no bbt exists at all then the device is scanned for factory marked
-+ * good / bad blocks and the bad block tables are created.
-+ *
-+ * For manufacturer created bbts like the one found on M-SYS DOC devices
-+ * the bbt is searched and read but never created
-+ *
-+ * The autogenerated bad block table is located in the last good blocks
-+ * of the device. The table is mirrored, so it can be updated eventually.
-+ * The table is marked in the oob area with an ident pattern and a version
-+ * number which indicates which of both tables is more up to date.
-+ *
-+ * The table uses 2 bits per block
-+ * 11b: block is good
-+ * 00b: block is factory marked bad
-+ * 01b, 10b: block is marked bad due to wear
-+ *
-+ * The memory bad block table uses the following scheme:
-+ * 00b: block is good
-+ * 01b: block is marked bad due to wear
-+ * 10b: block is reserved (to protect the bbt area)
-+ * 11b: block is factory marked bad
-+ *
-+ * Multichip devices like DOC store the bad block info per floor.
-+ *
-+ * Following assumptions are made:
-+ * - bbts start at a page boundary, if autolocated on a block boundary
-+ * - the space neccecary for a bbt in FLASH does not exceed a block boundary

-- * Fixed typo.
-- *
-- * Revision 1.3 2003/06/02 12:51:27 johana
-- * Now compiles.
-- * Commented some include files that probably can be removed.
-- *
-- * Revision 1.2 2003/06/02 12:09:41 johana
-- * Ported to ETRAX FS using the trig interrupt instead of timer1.
-- *
-- * Revision 1.3 2002/12/12 08:26:32 starvik
-- * Don't use C-comments inside CVS comments
-- *

-- * Fast timers (from Linux 2.4)
-- *
-- * Revision 1.5 2002/10/15 06:21:39 starvik
-- * Added call to init_waitqueue_head
-- *
-- * Revision 1.4 2002/05/28 17:47:59 johana
-- * Added del_fast_timer()
-- *
-- * Revision 1.3 2002/05/28 16:16:07 johana
-- * Handle empty fast_timer_list
-- *
-- * Revision 1.2 2002/05/27 15:38:42 johana
-- * Made it compile without warnings on Linux 2.4.
-- * (includes, wait_queue, PROC_FS and snprintf)
-- *
-- * Revision 1.1 2002/05/27 15:32:25 johana
-- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
-- *
-- * Revision 1.8 2001/11/27 13:50:40 pkj
-- * Disable interrupts while stopping the timer and while modifying the
-- * list of active timers in timer1_handler() as it may be interrupted
-- * by other interrupts (e.g., the serial interrupt) which may add fast
-- * timers.
-- *
-- * Revision 1.7 2001/11/22 11:50:32 pkj
-- * * Only store information about the last 16 timers.
-- * * proc_fasttimer_read() now uses an allocated buffer, since it
-- * requires more space than just a page even for only writing the
-- * last 16 timers. The buffer is only allocated on request, so
-- * unless /proc/fasttimer is read, it is never allocated.
-- * * Renamed fast_timer_started to fast_timers_started to match
-- * fast_timers_added and fast_timers_expired.
-- * * Some clean-up.
-- *
-- * Revision 1.6 2000/12/13 14:02:08 johana
-- * Removed volatile for fast_timer_list
-- *
-- * Revision 1.5 2000/12/13 13:55:35 johana
-- * Added DEBUG_LOG, added som cli() and cleanup
-- *
-- * Revision 1.4 2000/12/05 13:48:50 johana
-- * Added range check when writing proc file, modified timer int handling
-- *
-- * Revision 1.3 2000/11/23 10:10:20 johana
-- * More debug/logging possibilities.
-- * Moved GET_JIFFIES_USEC() to timex.h and time.c
-- *
-- * Revision 1.2 2000/11/01 13:41:04 johana
-- * Clean up and bugfixes.
-- * Created new do_gettimeofday_fast() that gets a timeval struct
-- * with time based on jiffies and *R_TIMER0_DATA, uses a table
-- * for fast conversion of timer value to microseconds.
-- * (Much faster the standard do_gettimeofday() and we don't really
-- * wan't to use the true time - we wan't the "uptime" so timers don't screw up
-- * when we change the time.
-- * TODO: Add efficient support for continuous timers as well.
-- *
-- * Revision 1.1 2000/10/26 15:49:16 johana
-- * Added fasttimer, highresolution timers.

-+ * On ETRAX FS, an interrupt remains latched and active until ack:ed.
-+ * Further, ATA acks are without effect as long as INTRQ is asserted, as the

-+ * clearing ack at the usual cris_ide_ack_intr call, but that serves just to
-+ * gracefully handle an actual spurious interrupt or similar situation (which
-+ * will cause an early return without further actions, see the ide_intr
-+ * function).
-+ *
-+ * However, the normal case at time of this writing is that nothing has

-+ * the condition desc->irqs_unhandled > 99900 in
-+ * kernel/irq/spurious.c:note_interrupt and the system will halt.
-+ *
-+ * To actually get rid of the interrupt corresponding to the current INTRQ
-+ * assertion, we make a second ack after the next ATA register read or write;
-+ * i.e. when INTRQ must be deasserted. At that time, we don't have the hwif
-+ * pointer available, so we need to stash a local copy (safe, because it'll be

-+ * Regarding RS485 operation in crisv32 serial driver.
-+ * ---------------------------------------------------
-+ * RS485 can be run in two modes, full duplex using four wires (485FD) and
-+ * half duplex using two wires (485HD). The default mode of each serial port
-+ * is configured in the kernel configuration. The available modes are:
-+ * RS-232, RS-485 half duplex, and RS-485 full duplex.
-+ *
-+ * In the 485HD mode the direction of the data bus must be able to switch.
-+ * The direction of the transceiver is controlled by the RTS signal. Hence
-+ * the auto_rts function in the ETRAX FS chip is enabled in this mode, which
-+ * automatically toggle RTS when transmitting. The initial direction of the
-+ * port is receiving.
-+ *
-+ * In the 485FD mode two transceivers will be used, one in each direction.
-+ * Usually the hardware can handle both 485HD and 485FD, which implies that
-+ * one of the transceivers can change direction. Consequently that transceiver
-+ * must be tied to operate in the opposite direction of the other one, setting
-+ * and keeping RTS to a fixed value do this.
-+ *
-+ * There are two special "ioctl" that can configure the ports. These two are
-+ * left for backward compatible with older applications. The effects of using
-+ * them are described below:
-+ * The TIOCSERSETRS485:
-+ * This ioctl sets a serial port in 232 mode to 485HD mode or vise versa. The
-+ * state of the port is kept when closing the port. Note that this ioctl has no
-+ * effect on a serial port in the 485FD mode.
-+ * The TIOCSERWRRS485:
-+ * This ioctl set a serial port in 232 mode to 485HD mode and writes the data
-+ * "included" in the ioctl to the port. The port will then stay in 485HD mode.
-+ * Using this ioctl on a serial port in the 485HD mode will transmit the data
-+ * without changing the mode. Using this ioctl on a serial port in 485FD mode
-+ * will not change the mode and simply send the data using the 485FD mode.

-- to guarantee that control traffic gets 10% of the bandwidth, and periodic transfer may
-- allocate the rest (90%). This doesn't work though. Read on for a lenghty explanation.
--
-- While there is a difference between rev. 2 and rev. 3 of the ETRAX 100LX regarding the NAK
-- behaviour, it doesn't solve this problem. What happens is that a control transfer will not
-- be interrupted in its data stage when PSTART happens (the point at which periodic traffic
-- is started). Thus, if PSTART is set to 10800 and its IN or OUT token is NAKed until just before
-- PSTART happens, it will continue the IN/OUT transfer as long as it's ACKed. After it's done,
-- there may be too little time left for an isochronous transfer, causing an epid attention
-- interrupt due to perror. The work-around for this is to let the control transfers run at the
-- end of the frame instead of at the beginning, and will be interrupted just fine if it doesn't
-- fit into the frame. However, since there will *always* be a control transfer at the beginning
-- of the frame, regardless of what we set PSTART to, that transfer might be a 64-byte transfer
-- which consumes up to 15% of the frame, leaving only 85% for periodic traffic. The solution to
-- this would be to 'dummy allocate' 5% of the frame with the usb_claim_bandwidth function to make
-- sure that the periodic transfers that are inserted will always fit in the frame.
--
-- The idea was suggested that a control transfer could be split up into several 8 byte transfers,
-- so that it would be interrupted by PSTART, but since this can't be done for an IN transfer this
-- hasn't been implemented.
--
-- The value 11960 is chosen to be just after the SOF token, with a couple of bit times extra

-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+ By default SquashFS caches the last 3 fragments read from
-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.
-+
-+config SQUASHFS_VMALLOC
-+ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED

-+ By default SquashFS uses kmalloc to obtain fragment cache memory.
-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ *
-+ * The first version was written by Martin Devera, <devik@cdi.cz>
-+ *
-+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
-+ * - Fix "Dead-loop on netdevice imq"-issue
-+ * Marcel Sebek <sebek64@post.cz>
-+ * - Update to 2.6.2-rc1
-+ *
-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
-+ * the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with
-+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ * I didn't forget anybody). I apologize again for my lack of time.

-+
-+2005-09-21 Markus Klotzbuecher <mk@mary>
-+
-+ * new release 0.6.1
-+
-+ * fix of a compiler warning due to changes in 2.6.13
-+
-+2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
-+
-+ * file.c: readdir: fix for a bug that caused directory entries
-+ to show up twice when using storage filesystems such as
-+ minixfs or pramfs.
-+
-+2005-06-30 Eric Lammerts <eric@lammerts.org>
-+
-+ * fix for an oops when overwriting a binary thats beeing
-+ executed.
-+
-+2005-06-09 <mk@mary>
-+
-+ * Renamed overlay to mini_fo-overlay.
-+
-+ * Added mini_fo-merge script to allow merging of storage and base
-+ after making modifications.
-+
-+2005-05-22 root <mk@mary>
-+
-+ * Added overlay script that allows to easily mount mini_fo ontop
-+ of a given base directory
-+
-+2005-05-10 <mk@mary>
-+
-+ * inode.c: xattr functions return -EOPNOSUPP instead of
-+ -ENOSUPP, what confuses "ls -l"
-+
-+ * Changed license from LGPL to GPL.
-+
-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release: mini_fo-0.6.1 (v0-6-1)
-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-+ depends on YAFFS_FS
-+ default y
-+ help
-+ Enable YAFFS1 support -- yaffs for 512 byte / page devices
-+
-+ If unsure, say Y.
-+
-+config YAFFS_DOES_ECC
-+ bool "Lets Yaffs do its own ECC"
-+ depends on YAFFS_FS && YAFFS_YAFFS1
-+ default n
-+ help
-+ This enables Yaffs to use its own ECC functions instead of using
-+ the ones from the generic MTD-NAND driver.
-+
-+ If unsure, say N.
-+
-+config YAFFS_ECC_WRONG_ORDER
-+ bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
-+ depends on YAFFS_FS && YAFFS_DOES_ECC
-+ default n
-+ help
-+ This makes yaffs_ecc.c use the same ecc byte order as
-+ Steven Hill's nand_ecc.c. If not set, then you get the
-+ same ecc byte order as SmartMedia.
-+
-+ If unsure, say N.
-+
-+config YAFFS_YAFFS2
-+ bool "2048 byte (or larger) / page devices"
-+ depends on YAFFS_FS
-+ default y
-+ help
-+ Enable YAFFS2 support -- yaffs for >= 2048 byte / page larger devices
-+
-+ If unsure, say Y.
-+
-+config YAFFS_AUTO_YAFFS2
-+ bool "Autoselect yaffs2 format"
-+ depends on YAFFS_YAFFS2
-+ default y
-+ help
-+ Without this, you need to explicitely use yaffs2 as the file
-+ system type. With this, you can say "yaffs" and yaffs or yaffs2
-+ will be used depending on the device page size.
-+
-+ If unsure, say Y.
-+
-+config YAFFS_DISABLE_LAZY_LOAD
-+ bool "Disable lazy loading"
-+ depends on YAFFS_YAFFS2
-+ default n
-+ help
-+ "Lazy loading" defers loading file details until they are
-+ required. This saves mount time, but makes the first look-up
-+ a bit longer.
-+
-+ Lazy loading will only happen if enabled by this option being 'n'
-+ and if the appropriate tags are available, else yaffs2 will
-+ automatically fall back to immediate loading and do the right
-+ thing.
-+
-+ Lazy laoding will be required by checkpointing.
-+
-+ Setting this to 'y' will disable lazy loading.
-+
-+ If unsure, say N.
-+
-+config YAFFS_DISABLE_WIDE_TNODES
-+ bool "Turn off wide tnodes"
-+ depends on YAFFS_FS
-+ default n
-+ help
-+ Wide tnodes are only used for large NAND arrays (>=32MB for
-+ 512-byte page devices and >=128MB for 2k page devices). They use
-+ slightly more RAM but are faster since they eliminate chunk group
-+ searching.
-+
-+ Setting this to 'y' will force tnode width to 16 bits and make
-+ large arrays slower.
-+
-+ If unsure, say N.
-+
-+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
-+ bool "Force chunk erase check"
-+ depends on YAFFS_FS
-+ default n
-+ help
-+ Normally YAFFS only checks chunks before writing until an erased
-+ chunk is found. This helps to detect any partially written chunks
-+ that might have happened due to power loss.
-+
-+ Enabling this forces on the test that chunks are erased in flash
-+ before writing to them. This takes more time but is potentially a
-+ bit more secure.
-+
-+ Suggest setting Y during development and ironing out driver issues
-+ etc. Suggest setting to N if you want faster writing.
-+
-+ If unsure, say Y.
-+
-+config YAFFS_SHORT_NAMES_IN_RAM
-+ bool "Cache short names in RAM"
-+ depends on YAFFS_FS
-+ default y
-+ help
-+ If this config is set, then short names are stored with the
-+ yaffs_Object. This costs an extra 16 bytes of RAM per object,
-+ but makes look-ups faster.
-+
-+ If unsure, say Y.
