cmd_nand: fix crashing bug in nand read/write

2012-06-08T19:57:24+00:00

Commit 418396e212b59bf907dbccad997ff50f7eb61b16 introduced a
bug that causes nand read and nand write to crash in strcmp
due to a null pointer.

Root cause is that strchr(cmd, '.') returns a null pointer when
the input string does not contain a '.'

The strcmp function does not check for null pointers, resulting
in a crash.

nand: extend .raw accesses to work on multiple pages

2012-05-18T22:34:31+00:00

A use for this is to read, modify, erase, and write an entire block as a
single unit, as a replacement for the biterr command.  This way gives
more flexibility in that you can also test multiple bit errors, errors
in the ECC, etc.

bootstage: Replace show_boot_progress/error() with bootstage_...()

2012-03-18T20:41:39+00:00

These calls should not be made directly any more, since bootstage
will call the show_boot_...() functions as needed.

bootstage: Convert NAND progress numbers to enums

2012-03-18T20:27:20+00:00

This changes over the NAND progress numbers to use enums from
bootstage.h.

bootstage: Use show_boot_error() for -ve progress numbers

2012-03-18T19:56:00+00:00

Rather than the caller negating our progress numbers to indicate an
error has occurred, which seems hacky, add a function to indicate this.

Convert cmd_usage() calls in common to use a return value

2012-03-06T20:09:46+00:00

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

cmd_nand.c: Fix 'nand dump' after latest MTD resync

2012-02-28T20:04:54+00:00

With 2a8e0fc nand_do_read_ops changed in behavior slightly (keeping in sync
with the kernel which did this change in b64d39d8) such that the OOB data is
always copied into oobbuf and never appended to datbuf.  Within U-Boot only
the nand_dump function (for the dump nand subcommand) was expecting the OOB
data to only be appended to datbuf.  So we now change nand_dump to not
malloc extra space, correct the comment about datbuf and OOB data and switch
the pointer to oobbuf before printing.

NAND: Make page, erase, oob size available via cmd_nand

2011-10-03T23:35:12+00:00

The "nand info" and "nand device" now set shell/environment variables:
	nand_writesize ... nand page size
	nand_oobsize ..... nand oob area size
	nand_erasesize ... nand erase block size

Also, the "nand info" command now displays this info.
