generalized and tested on the ST-Ericsson U300. It probably
easily works on the NHK8815 too.

Adding a new flash definition would need less code.
Keep the platform passing flash definition method.
If one flash is both defined in platform data and builtin table,
driver would select the one from platform data first.

By this way, platform could select the timing most suit for itself,
not need to follow the common settings.

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.

The current ndfc driver only compiles under arch/ppc. This arch was
removed from the kernel. I notice the event entry for the ndfc in
Kconfig has been removed in 2.6.28.

This patch converts the ndfc to a proper OF (OpenFirmware) driver. I
can give a working example of the DTS if needed.

The patch has been in production use on the PIKA Warp Appliance and is
in use by others. The Warp basically boots from NAND, so the ndfc driver
is very important to us.
