Håvard Skinnemoen d4f4c0aa8e [MTD] [NAND] rename at91_nand -> atmel_nand: file names and Kconfig
The AT91 NAND driver needs just a few tiny modifications to work on
AVR32 as well. Rename it atmel_nand to reflect this.

Also move the ECC register definitions into drivers/mtd/nand since they
are only useful to the atmel_nand driver, and get rid of the useless
filename at the top of each file.

Adrian Bunk 59018b6d2a MTD/JFFS2: remove CVS keywords
Once upon a time, the MTD repository was using CVS.

This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.

This also includes code that printed them to the user.

Anton Vorontsov 5c249c5a57 [MTD] [NAND] FSL UPM NAND driver
This is very simple driver, NAND is connected through localbus,
and User-Programmable Machine is doing various adjustments to
speak NAND. No special efforts needed to do read and write cycles,
though to control ALE and CLE phases, we ask UPM to generate exact
pre-programmed signals on the localbus lines.

eric miao fe69af002e [MTD] [NAND] support for pxa3xx
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 :-)

Bryan Wu b37bde1478 [MTD] [NAND] Blackfin on-chip NAND Flash Controller driver
This is the driver for latest Blackfin on-chip nand flash controller

 - use nand_chip and mtd_info common nand driver interface
 - provide both PIO and dma operation
 - compiled with ezkit bf548 configuration
 - use hardware 1-bit ECC
 - tested with YAFFS2 and can mount YAFFS2 filesystem as rootfs

ChangeLog from try#1
 - use hweight32() instead of count_bits()
 - replace bf54x with bf5xx and BF54X with BF5XX
 - compare against plat->page_size in 2 cases when enable hardware ECC

ChangeLog from try#2
 - passed nand_test suites
 - use cpu_relax() instead of busy wait loop
 - some coding style issue pointed out by Andrew

Jörn Engel e208520ed6 [MTD] [NAND] Driver for Olympus MAUSB-10 and Fujifilm DPC-R1 card readers
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).

The TS-72xx is a series of embedded single board computers from
Technologic Systems based on the Cirrus ep93xx (arm920t based) CPU.

The TS-7200 uses NOR flash, while all the other models in the series
(TS-7250, TS-7260) use NAND flash -- included is a driver for the NAND
flash on those boards.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
