76c23c32e3 mtd: nand: fix ECC Correction bug for SMC ordering for NDFC driver
Fix ECC Correction bug where the byte offset location were double
fliped causing correction routine to toggle the wrong byte location
in the ECC segment. The ndfc_calculate_ecc routine change the order
of getting the ECC code.
        /* The NDFC uses Smart Media (SMC) bytes order */
        ecc_code[0] = p[2];
        ecc_code[1] = p[1];
        ecc_code[2] = p[3];
But in the Correction algorithm when calculating the byte offset
location, the b1 is used as the upper part of the address. Which
again reverse the order making the final byte offset address
location incorrect.
	byte_addr = (addressbits[b1] << 4) + addressbits[b0];
The order is change to read it in straight and let the correction
function to revert it to SMC order.

f12a947328 mtd: nand: DaVinci: Add 4-bit ECC support for large page NAND chips
This patch adds 4-bit ECC support for large page NAND chips using the new
ECC mode NAND_ECC_HW_OOB_FIRST.  The platform data from board-dm355-evm
has been adjusted to use this mode.

The patches have been verified on DM355 device with 2KiB-page Micron
devices using mtd-tests and JFFS2.  Error correction up to 4 bits has
also been verified using nandwrite/nanddump utilities.

This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to
support 4-bit ECC on TI DaVinci devices with large page (up to 2KiB) NAND
chips.  This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.

"ECC_HW_OOB_FIRST" name suggested by Thomas Gleixner

f33dabbe79 mtd: nand: register orion_nand using platform_driver_probe()
orion_nand_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g.  via sysfs) results in an oops.

As requested by Nicolas Pitre platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.  This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

272023df26 mtd: nand: Fix memory leak on txx9ndfmc probe failure.
Commit 81933046ef ('mtd: Fix handling of
mtdname in txx9ndfmc.c') introduced a potential memory leak. The
'mtdname' member of the private data structure is now allocated
separately, but was not freed on certain error paths.

Fix that, and make things simpler by _always_ allocating it separately
so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'...
which gets ugly now that we're doing it more than once, and more likely
that we'll get it wrong some time.

9db41f9edc [MTD] [NAND] S3C2410: Allow the machine code to get the BBT table from NAND
Added a flag to allow the machine code to tell the NAND
subsystem that it should try to pickup a BBT from the flash,
and also skip the NAND full scan at startup.

c3a9f35673 mtd: blackfin NFC: fix hang when using NAND on BF527-EZKITs
The DMAs have different bit sizes on BF52x and BF54x.  From the PHRM:

"The 16-bit DMA Access Bus (DAB) connects the DMA controller to the
on-chip peripherals, PPI, SPI, Ethernet MAC, the SPORTs, NFC,
HOSTDP and the UARTs."

32-bit DMA won't work for BF52x.

f36e20c01a mtd: plat_nand: allow platform to set partitions
Add optional callback to allow platform to initialize partitions.

Static partitions on a nand device could vary depending on the size of the
device.  This patch allows an optional platform callback to be used to
setup this partition information at runtime.

Scan order is:
	1) chip.part_probe_types
	2) chip.set_parts
	3) chip.partitions
	4) full mtd device (fallback for no partitions)

Some of the existing nand drivers could possibly be replaced by the
plat_nand driver by using this patch.  These include autcpu12.c and
ts7250.c drivers.

bf95efd41b mtd: plat_nand: add platform probe/remove callbacks
Add optional probe and remove callbacks to the plat_nand driver.

Some platforms may require additional setup, such as configuring the
memory controller, before the nand device can be accessed.  This patch
provides an optional callback to handle this setup as well as a callback
to teardown the setup.

d6fed9e9fc mtd: extend plat_nand for (read|write)_buf
This patch adds (write|read)_buf callbacks to plat_nand.

The NAND on the TS-7800 provisioned by the FPGA allows readw() and
readl() to be used which gives a 2.5x speed up.  To be able to use this
from the plat_nand driver a hook for read_buf (and also write_buf whilst
we are in there) need to be made available.  This patch adds the hook.
