Changes since U-Boot 1.1.4:
======================================================================
-* Fix dbau1x00 Board
- - Fix dbau1x00 boards broken by dbau1550 patch
- PLL:s were not set for boards other than 1550.
- Flash CFI caused card to hang due to undefined CFG_FLASH_BANKS_LIST.
- Default boot is now bootp for cards other than 1550.
- Patch by Thomas Lange Aug 10 2005
-* Fixes common/cmd_flash.c:
+* Some code cleanup
- - fix some compiler/parser error, if using m68k tool chain
- - optical fix for protect on/off all messages, if using more
- then one bank
- Patch by Jens Scharsig, 28 July 2005

* Fix Quad UART mapping on MCC200 board due to new HW revision
* Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)
405 SDRAM: - The SDRAM parameters can now be defined in the board
- config file and the 405 SDRAM controller values will
- be calculated upon bootup (see PPChameleonEVB).
- When those settings are not defined in the board
- config file, the register setup will be as it is now,
- so this implementation should not break any current
- design using this code.

Patch by Stefan Roese, 17 Mar 2006
are removed from the default U-Boot build.
Enable DEBUG for lib_arm/board.c to enable debug messages.
New CONFIG_DISPLAY_CPUINFO and CONFIG_DISPLAY_BOARDINFO options.

+ Patch by Stefan Roese, 24 Jan 2006
* Fix various compiler warnings on ppc4xx builds (ELDK 4.0)
Patch by Stefan Roese, 18 Jan 2006
* Add support for multiple PHYs.
Tested on the following boards:
- cmcpu2 (at91rm9200/ether.c)
+ cmcpu2 (at91rm9200/ether.c)
PPChameleon (ppc4xx/4xx_enet.c)
- yukon (mpc8220/fec.c)
- uc100 (mpc8xx/fec.c)
- tqm834x (mpc834x/tsec.c) with EEPRO100
+ yukon (mpc8220/fec.c)
+ uc100 (mpc8xx/fec.c)
+ tqm834x (mpc834x/tsec.c) with EEPRO100
lite5200 (mpc5xxx/fec.c) with EEPRO100 card (drivers/eepro100.c)
Main changes include:
common/miiphyutil.c
The first one is to define a single, static partition:
#undef CONFIG_JFFS2_CMDLINE
- #define CONFIG_JFFS2_DEV "nor0"
- #define CONFIG_JFFS2_PART_SIZE 0xFFFFFFFF /* use whole device */
- #define CONFIG_JFFS2_PART_SIZE 0x00100000 /* use 1MB */
- #define CONFIG_JFFS2_PART_OFFSET 0x00000000
+ #define CONFIG_JFFS2_DEV "nor0"
+ #define CONFIG_JFFS2_PART_SIZE 0xFFFFFFFF /* use whole device */
+ #define CONFIG_JFFS2_PART_SIZE 0x00100000 /* use 1MB */
+ #define CONFIG_JFFS2_PART_OFFSET 0x00000000
The second method uses the mtdparts command line option and dynamic
partitioning:
/* mtdparts command line support */
#define CONFIG_JFFS2_CMDLINE
- #define MTDIDS_DEFAULT "nor1=zuma-1,nor2=zuma-2"
- #define MTDPARTS_DEFAULT "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"
+ #define MTDIDS_DEFAULT "nor1=zuma-1,nor2=zuma-2"
+ #define MTDPARTS_DEFAULT "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"
Command line of course produces bigger images, and may be inappropriate
for some targets, so by default it's off.
Bring ARM memory layout in sync with the documentation:
stack and malloc-heap are now located _below_ the U-Boot code
-* Accelerate booting on TRAB board: read and check autoupdate image
+* Accelerate booting on TRAB board: read and check autoupdate image
headers first instead of always reading the whole images.
* Fix type in MPC5XXX code (pointed out by Victor Wren)
* Make 5200 reset command _really_ reset the board, without running
any other code after it
-* Fix errors with flash erase when range spans across banks
+* Fix errors with flash erase when range spans across banks
that are mapped in reverse order
* Fix flash mapping and display on P3G4 board
or 1 x AM29LV652 (two LV065 in one chip = 16 MB);
Run IPB at 133 Mhz; adjust the MII clock frequency accordingly
-* Set BRG_CLK on PM825/826 to 64MHz (VCO_OUT / 4, instead of 16 MHz)
+* Set BRG_CLK on PM825/826 to 64MHz (VCO_OUT / 4, instead of 16 MHz)
to allow for more accurate baudrate settings
(error now 0.7% at 115 kbps, instead of 3.5% before)
Update for MPC8266ADS board
* Get (mostly) rid of CFG_MONITOR_LEN definition; compute real length
- instead CFG_MONITOR_LEN is now only used to determine _at_compile_
+ instead CFG_MONITOR_LEN is now only used to determine _at_compile_
_time_ (!) if the environment is embedded within the U-Boot image,
or in a separate flash sector.
* Patch by Thomas Schäfer, 28 Apr 2003:
Fix SPD handling for 256 ECC DIMM on Walnut
-* Add support for arbitrary bitmaps for TRAB's VFD command;
+* Add support for arbitrary bitmaps for TRAB's VFD command;
allow to pass boot bitmap addresses in environment variables;
allow for zero boot delay
* Add VFD type detection to trab board
-* extend drivers/cs8900.c driver to synchronize ethaddr environment
+* extend drivers/cs8900.c driver to synchronize ethaddr environment
variable with value in the EEPROM
* Patch by Stefan Roese, 10 Feb 2003:
* Patch by Pierre Aubert, 05 Nov 2002
Add support for slave serial Spartan 2 FPGAs
-* Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
+* Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
drivers
* Add support for log buffer which can be passed to Linux kernel's
