2011-01-06	mtd: txx9ndfmc: limit transfer bytes to 512 (ECC provides 6 bytes max)	Ralf Rösch	1	-2/+3
	See commit: c0cbfd0e81d879a950ba6f0df3f75ea30c5ab16e Using __nand_correct_data() helper function, this driver can read 512 byte (with 6 byte ECC) at a time. This is correct, but not more: With NAND chips providing page sizes > 512 Bytes chip->ecc.bytes are calculated > 6 in txx9ndfmc_nand_scan. According the data sheet there are (only) 6 bytes ECC available. After applying the patch a Hynix 512M*8 with 2KiB page size could be successfully formatted and used with an ubifs file system.

2009-09-19	mtd: nand: txx9ndfmc: transfer 512 byte at a time if possible	Atsushi Nemoto	1	-5/+47
	Using __nand_correct_data() helper function, this driver can read 512 byte (with 6 byte ECC) at a time. This results minor performance improvement. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-06-09	mtd: nand: Fix memory leak on txx9ndfmc probe failure.	Atsushi Nemoto	1	-9/+9
	Commit 81933046ef2a615031c46171013bde2c5225ee69 ('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.

2009-05-29	mtd: Fix handling of mtdname in txx9ndfmc.c	David Woodhouse	1	-4/+12
	As pointed out by Kay Sievers, the name size limit is gone from the driver-core, and BUS_ID_SIZE is obsolescent. Rather than just papering over the problem by replacing the mtdname array size with an arbitrary '20 + 2', fix the problem properly and handle arbitrary name sizes.

2009-03-20	[MTD] TXx9 SoC NAND Flash Memory Controller driver	Atsushi Nemoto	1	-0/+428
	This patch adds support for the integrated NAND flash controller of the TXx9 family. Once upon a time there were tx4925ndfmc and tx4938ndfmc driver. They were removed due to bitrot in 2005. This new driver is completely rewritten based on a driver in CELF patch archive.
