Tacls can actually be zero with some NAND flash devices, so we need
to permit this.
Also, the TACLS register actually specifies the actual number of
HCLK clocks, where the TWRPH0 and TWRPH1 registers are auto-incremented
by one HCLK clock in hardware.

fix-s3c-nand-read-bytes.patch
With the introduction of optimized OOB reads in nand_read_subpage,
the length of the data requested may not be a multiple of four bytes.
This caused a partial read on the 2440, leading to false ECC errors
and, worse, attempts to "correct" them.
Note that there is a similar issue in s3c2440_nand_write_buf, which
doesn't seem to cause trouble yet.

Subject: [PATCH] [gta02] Disable hardware ECC unless we get instructed to enable it
This is restoring the old behavior in regard to ECC. Even if
hardware ECC was compiled in we didn't use it. Make this a runtime
option. If the bootloader passes hardware_ecc we will enable the
hardware ECC for real.

[JFFS2] fix race condition in jffs2_lzo_compress()

[MTD] [NAND] OMAP2: remove duplicated #include

For "unlock" cycles to 16bit devices in 8bit compatibility mode we need
to use the byte addresses 0xaaa and 0x555. These effectively match
the word address 0x555 and 0x2aa, except the latter has its low bit set.
Most chips don't care about the value of the 'A-1' pin in x8 mode,
but some -- like the ST M29W320D -- do. So we need to be careful to
set it where appropriate.
cfi_send_gen_cmd is only ever passed addresses where the low byte
is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are
affected by this patch, by masking in the extra low bit when the device
is known to be in compatibility mode.
[dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa]
v4: Fix stupid typo in cfi_build_cmd_addr that failed to compile
I'm writing this patch way to late at night.
v3: Bring all of the work back into cfi_build_cmd_addr
including calling of map_bankwidth(map) and cfi_interleave(cfi)
So every caller doesn't need to.
v2: Only modified the address if we our device_type is larger than our
bus width.

To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both. That's this changeset.
2) for each driver convert to new methods. *ALL* drivers
are converted in this series.
3) kill the old (renamed) methods.
Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain. The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.
New methods:
open(bdev, mode)
release(disk, mode)
ioctl(bdev, mode, cmd, arg) /* Called without BKL */
compat_ioctl(bdev, mode, cmd, arg)
locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */

This reverts commit 75d0ee2202b5740e94e913d8a52f91c6557c4c81.
Although it seems ObviouslyCorrect™, the spi_write() call uses DMA,
while spi_write_then_read() does not. Since our buffer is on the stack,
we must use the latter even though we don't actually want to read
anything back.

The CFI information read from AT49BV6416 lists the erase regions in the
wrong order, causing problems when trying to erase or update the first
or last 64KiB block.
Work around this by inverting the "top boot" flag, which will
effectively reverse the order of the erase regions.
This chip is obsolete, but it's used in some existing designs.

This patch adds TopBottom detection for most Macronix chips with CFI V1.0.
The main purpose of this patch is to add detection of the MX29LV400C B
used on the LaCie Ethernet Disk mini V2 NAS.
It detects the following parts correctly:-
MX28F640C3B T
MX29LV002C B
MX29LV002NC B
MX29LV004C T
MX29LV400C T/B
MX29LV800C T/B
MX29LV160C T/B
MX29SL800C T/B
MX29SL802C T/B
It detects the following uniform part as bottom but it should work
correctly:-
MX29LV040C
For T parts it causes the erase block table to be reversed correctly.
For other parts it avoids the bogus "Assuming top" message.
It does not detect the following correctly:-
MX28F640C3B B
MX29LV002C T
MX29LV002NC T
MX29LV004C B
MX29SL400C T/B
MX29SL402C T/B
If desired I could supply a more complicated patch to handle these as
well.
Only the MX29LV400C B has been physically tested; others were checked
against their data sheets.

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.
This is all fairly brainless/obvious stuff. Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads. (That would improve
with hardware IRQ debouncing enabled, of course...)

The functions that write the OOB info (on hardware ECC only) use the
HW_SYNDROME method.
This is not correct : the start position is "pos = eccsize + chunk" and
should be eccsize. So, the standard (nand_write_oob_std) function should
be used. This patch corrects this by using NAND_ECC_HW instead of
NAND_ECC_HW_SYNDROME.
This has only been tested on small pages nand flash.
(if anyone can test it on large pages that would be great).
