linux/compat.h: rename from linux/mtd/compat.h

This lets us use it in more places than just mtd code.

nand/fsl_elbc: Convert to self-init

2012-01-26T22:09:06+00:00

This driver doesn't yet make use of the added flexibility (not that that
should stop anyone from converting...), but it will with the in-progress
hack to support 4k-page NAND.

nand: Introduce CONFIG_SYS_NAND_SELF_INIT

2012-01-26T22:09:06+00:00

This allows a driver to run code between nand_scan_ident() and
nand_scan_tail(), among other things.  See the additions to
doc/README.nand for details.

To allow a gradual transition, Boards that don't set
CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but
new drivers should not require this, and existing drivers should be
converted when convenient.

nand: Add common functions to linux/mtd/nand.h

2011-12-06T22:59:31+00:00

Functions often used in SPL are now part of linux/mtd/nand.h.
Static modifiers are removed from these functions in
drivers/mtd/nand/nand_base.c.

nand_util: drop trailing all-0xff pages if requested

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

Add a flag to nand_read_skip_bad() such that if true, any trailing
pages in an eraseblock whose contents are entirely 0xff will be
dropped.

The implementation is via a new drop_ffs() function which is
based on the function of the same name from the ubiformat
utility by Artem Bityutskiy.

This is as-per the reccomendations of the UBI FAQ [1]

nand_util: treat WITH_YAFFS_OOB as a mode

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

When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an
operation which is mutually exclusive with the 'usual' way of writing.

Add a check that client code does not specify WITH_YAFFS_OOB along with any
other flags and add a comment indicating that the WITH_YAFFS_OOB flag should
not be mixed with other flags.

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);

NAND: add the ability to directly write yaffs image

2011-01-12T23:13:10+00:00

This patch add addition suffix to nand write to give the uboot
the power to directly burn the yaffs image to nand.
