nand: yaffs: Remove the "nand write.yaffs" command
This command is only enabled by one board, complicates the NAND code,
and doesn't appear to have been functioning properly for several
years. If there are no bad blocks in the NAND region being written
nand_write_skip_bad() will take the shortcut of calling nand_write()
which bypasses the special yaffs handling. This causes invalid YAFFS
data to be written. See
http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for
an example and a potential workaround.
U-Boot still retains the ability to mount and access YAFFS partitions
via CONFIG_YAFFS2.

omap: gpmc: 'nandecc sw' can use HAM1 or BCH8
The 'nandecc sw' command selects a software-based error correction
algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some
platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their
software-based correction algorithm. Allow a user to be specific e.g.
# nandecc sw <hamming|bch8>
where 'hamming' is still the default.
Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set
to a hardware-based ECC scheme---a little strange when the user
has requested 'sw' ECC.

mtd: nand: do not scan BBT after scrub
Currently, "nand scrub" runs chip->scan_bbt at the end of
nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set.
It violates the intention of NAND_SKIP_BBTSCAN.
Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that
chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set.
Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt()
right after scrub. We can be lazier here because the BBT is scanned
at the next call of nand_block_checkbad().

mtd: nand: Mark the BBT as scanned prior to calling scan_bbt again
Commit 35c204d8a9d0 (nand: reinstate lazy bad block scanning)
broke NAND_BBT_USE_FLASH feature.
Its git-log claimed that it reinstated the change as by commit
fb49454b1b6c ("nand: reinstate lazy bad block scanning"), but it moved
"chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);".
It causes recursion if scan_bbt does not find a flash based BBT
and tries to write one, and the attempt to erase the BBT area
causes a bad block check.
Reinstate commit ff49ea8977b5 (NAND: Mark the BBT as scanned prior to
calling scan_bbt.).

mtd/nand/vf610_nfc: Disable subpage writes
This patch disables subpage writes for vf610_nfc nand
driver. This is required, as without this fix, writing
unaligned u-boot images with DFU results in a hang.
Trying to write unalgined binary images also results
in a hang, without disabling subpage writes.
Patch has been tested on a Colibri VF61 module.

mtd: denali: set some registers after nand_scan_ident()
Some but not all of implementations of the Denali NAND controller
have hardware circuits to detect the device parameters such as
page_size, erase_size, etc. Even on those SoCs with such hardware
supported, the hardware is known to detect wrong parameters for some
nasty (almost buggy) NAND devices. The device parameters detected
during nand_scan_ident() are more trustworthy.
This commit sets some hardware registers to mtd->pagesize,
mtd->oobsize, etc. in the code between nand_scan_ident() and
nand_scan_tail().

mtd: denali: use CONFIG_SYS_NAND_SELF_INIT
Some variants of the Denali NAND controller need some registers
set up based on the device information that has been detected during
nand_scan_ident().
CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between
nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce
the difference between this driver and its Linux counterpart because
this driver was ported from Linux. Moreover, doc/README.nand recommends
to use CONFIG_SYS_NAND_SELF_INIT.
