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.

NAND: Add -y option to nand scrub command

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

This allows the scrub command to scrub without asking the user if he really
wants to scrub the area. Useful in scripts.

autostart: unify duplicated logic into the bootm code

2011-07-25T20:18:26+00:00

Rather than having a bunch of random commands handle autostart behavior,
unify the logic in a single place.  This also fixes building of these

different commands when bootm is disabled.

cmd_nand: add nand write.trimffs command

2011-07-01T20:56:51+00:00

Add another nand write. variant, trimffs. This command will request of
nand_write_skip_bad() that all trailing all-0xff pages will be
dropped from eraseblocks when they are written to flash as-per the
reccommended behaviour of the UBI FAQ [1].

The function that implements this timming is the drop_ffs() function
by Artem Bityutskiy, ported from the mtd-utils tree.

nand_util: convert nand_write_skip_bad() to flags

2011-07-01T20:56:51+00:00

In a future commit the behaviour of nand_write_skip_bad()
will be further extended.

Convert the only flag currently passed to the nand_write_
skip_bad() function to a bitfield of only one allocated
member. This should avoid an explosion of int's at the
end of the parameter list or the ambiguous calls like

nand_write_skip_bad(info, offset, len, buf, 0, 1, 1);
nand_write_skip_bad(info, offset, len, buf, 0, 1, 0);

Instead there will be:

nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB |
			WITH_OTHER);

Revert "boot cmds: convert to getenv_yesno() with autostart"

2011-01-11T19:56:34+00:00

This reverts commit 5a442c0addc69d0c4b58e98e5aec1cf07576debb.

This commit changed the behaviour of getenv_yesno() (both the default
behaviour and the documented behaviour for abbreviated arguments)
which resulted in problems in several areas.
