The code checked only the ES revision of the chip, and hence incorrectly

Philippe De Muyter [Tue, 17 Aug 2010 16:40:25 +0000 (18:40 +0200)]
Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips.

I have "ported" U-boot to a in house made board with Numonyx Axcell P33/P30
256-Mbit 65nm flash chips.

After some time :( searching for bugs in our board or soft, we have
discovered that those chips have a small but annoying bug, documented in
"Numonyx Axcell P33/P30 256-Mbit Specification Update"

It states :
When customer uses [...] block unlock, the block lock status might be
altered inadvertently. Lock status might be set to either 01h or 03h
unexpectedly (00h as expected data), which leads to program/erase failure
on certain blocks.

A working workaround is given, which I have applied and tested with success :

Workaround:  If the interval between 60h and its subsequent command
     can be guaranteed within 20us, Option I is recommended,
     otherwise Option II (involves hardware) should be selected.
Option I: The table below lists the detail command sequences:
Command
      Data bus           Address bus       Remarks
Sequence
  1              90h            Block Address
   Read Lock Status
  2             Read         Block Address + 02h
 (2)(3)                                      (1)
3                60h           Block Address
 (2)(3)                                      (1)   Lock/Unlock/RCR Configuration
4           D0h/01h/03h        Block Address
Notes:
(1) Block Address refers to RCR configuration data only when the 60h
    command sequence is used to set RCR register combined with 03h
    subsequent command.
(2) For the third and fourth command sequences, the Block Address must
    be the same.
(3) The interval between 60h command and its subsequent D0h/01h/2Fh/03h
    commands should be less than 20us.

And here is a log comparison of a simple (destructive) flash test without

miiphy: leverage current_mii cache more

For code that uses miiphy_{read,write}, every call invokes a full look up
of the mii list.  There is already a "current_mii" cache that is used by
some code, but have the miiphy_{read,write} function use it as well.  This
does increase the code size slightly, but I think it's worth it.

14 years agofdt: Fix bug in size calculation in fdt_resize() with initrd use
Feng Wang [Tue, 3 Aug 2010 14:22:43 +0000 (16:22 +0200)]
fdt: Fix bug in size calculation in fdt_resize() with initrd use

Original bug description from Feng (fdt_resize() bug caused "WARNING:
could not set linux, initrd-start FDT_ERR_NOSPACE."):

What I got is an error: "WARNING: could not set linux,initrd-start
FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused
linux to miss init part.

After some digging, I found out the reason for this error, it is caused
by fdt_resize().

FDT blob got resized after filling in all board specific information of
PowerPC. (in boot_body_linux()). It reduced blob size with only extra
space for two fdt_reserve_entry, one for fdt itself, and one for initrd.
Then it's aligned to a 0x1000 page boundary. However, later in
fdt_initrd(), it could add two more properties, initrd-start AND
initrd-end, each one needs at least two fdt_reserve_entry sizes done by
_fdt_add_property() (name and value). Thus, the two fdt_reserve_entry
extra space is not sufficient.

So for some specific fdt size which is just under the page boundary
after resizing, this will cause an error of FDT_ERR_NOSPACE in
fdt_initrd() when setting those two properties, and failed to pass
initrd information to linux.

My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for
initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for
actual_totalsize, use 5*sizeof(struc fdt_reserve_entry).

Stefan: I got this same error on katmai, when trying to boot with
initrd (run flash_self). This patch fixes this issue.
