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.

do_bootm: unify duplicate prototypes

2010-11-28T20:45:32+00:00

The duplication of the do_bootm prototype has gotten out of hand,
and they're pretty much all outdated (wrt constness).  Unify them
all in command.h.

Fix warning in nand unlock command

2010-10-18T19:54:08+00:00

Commit ea533c260a801c4e51f92f75165cebe6d7b01e35 changed
arg_off_size to take a pointer to a device index, rather than
to the device itself.  When updating callers, the nand unlock
code was missed.

nand commands: make only "dump" repeatable.

2010-10-11T20:10:26+00:00

The dump command is made to increment its address on repeat,
as md does.  Other commands do not make sense to issue repeatedly,
and can be irritating when it happens accidentally, so don't.
