Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').
(Also some header file fallout - like so many merges this merge window -

This patch adds a driver for the M-Sys / Sandisk diskonchip G4 nand flash found
in various smartphones and PDAs, among them the Palm Treo680, HTC Prophet and
Wizard, Toshiba Portege G900, Asus P526, and O2 XDA Zinc. It was tested on the
Treo 680, but should work generically.
Since v3, this patch adds power management functions, a scan of the factory bad
block table during initialization, several fixes, and more extensive testing.
Also, the platform data header file, which only contained partitioning
information, was removed. Command-line partitioning can be used, at least until
an mtd parser is written for the saftl format with which these chips are
shipped.

This patch adds software BCH ECC support to mtd, in order to handle recent
NAND device ecc requirements (4 bits or more).
It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board
drivers, and a new Kconfig option to enable BCH support. It relies on the
generic BCH library introduced in a previous patch.
When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields
chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required
error correction capability. See nand_bch_init() documentation for details.
It has been tested on the following platforms using mtd-utils, UBI and
UBIFS: x86 (with nandsim), arm926ejs.

This adds a driver for Ricoh R5C852 xD card reader.
This reader is a part of larger mulifunction chip
and found at least in R5C832
Driver is complete, but bewere of the fact that some
(probably only type M) xD cards are 'fake' which means that
they have an on board CPU and expose emulated nand command set
These cards don't even store the oob area on the flash,
but generate it on the fly from something else.
Thus they demand to have proper values written in the oob area,
and therefore only useful with SmartMedia FTL.

This is a device driver for the NAND flash controller found on the various
DaVinci family chips. It handles up to four SoC chipselects, and some
flavors of secondary chipselect (e.g. based on upper bits of the address
bus) as used with some multichip packages. (Including the 2 GiB chips
used on some TI devel boards.)
The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but
not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as
available on chips like the DM355 or OMAP-L137 and needed with the more
error-prone MLC NAND chips.
This is a cleaned-up version of code that's been in use for several years
now; sanity checked with the new drivers/mtd/tests.

This is preliminary since:
1. It supports only _one_ chip select at the moment. As there is no
existing platforms available using two chip selects of the NAND
controller, it shall really not include code for supporting the
2nd chip select for now, as such code cannot be verified.
2. It resorts to the default and simpliest memory based badblock
table
3. Only limited types of nand flash are currently supported. Most
PXA3xx processors come with on-chip NAND flash dies, so there
isn't much flexibility for other types of NAND.
4. The NAND controller should be configured to detect the device's
ID, thus making it difficult to use nand_scan_ident() to assist
the detection process (though it's not impossible)
TODO: fix all the above limitations of cuz :-)

Unlike most stuff on the market the chip inside these two allows raw
flash access and doesn't implement and FTL, leaving that functionality
to the device driver.
Raw flash access in a cheap USB cardreader! An MTD test device one can
attach to a PC! What a deal!
The command set of the chip is not documented, so information was
obtained from the existing mass-storage driver
(drivers/usb/storage/alauda.c), its documentation
(http://alauda.sourceforge.net/wikka.php?wakka=BulkCommandReference),
additional reverse engineering and comparison with a vendor driver for a
related chip
(http://www.ratocsystems.com/english/download/driver/linux/sma03u.html).
