[MTD] Makefile fix for mtdsuper

2007-08-03T11:42:40Z

We want drivers/mtd/{mtdcore, mtdsuper, mtdpart}.c to be built and linked into the same mtd.ko module. Fix the Makefile to ensure this, and remove duplicate MODULE_ declarations in mtdpart.c, as mtdcore.c already has them. Signed-off-by: Satyam Sharma Signed-off-by: David Woodhouse

[MTD] Correct partition failed erase address

2007-03-08T10:45:04Z

If an erase operation fails, the address at which the failure occurred is returned by the driver. The MTD partition must adjust this address (by subtracting the partition offset) before returning to the caller. This was not happening, which caused JFFS2 to mark the wrong block bad!

[MTD] [NAND] make oobavail public

2007-03-08T09:17:43Z

During the MTD rework the oobavail parameter of mtd_info structure has become private. This is not quite correct in terms of integrity and logic. If we have means to write to OOB area, then we'd like to know upfront how many bytes out of OOB are spare per page to be able to adapt to specific cases. The patch inlined adds the public oobavail parameter. Signed-off-by: Vitaly Wool Signed-off-by: David Woodhouse

[MTD] remove unused ecctype,eccsize fields from struct mtd_info

2007-02-09T15:27:12Z

Remove unused and broken mtd->ecctype and mtd->eccsize fields from struct mtd_info. Do not remove them from userspace API data structures (don't want to breake userspace) but mark them as obsolete by a comment. Any userspace program which uses them should be half-broken anyway, so this is more about saving data structure size. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

[MTD] NAND: add subpage write support

2006-11-29T15:03:52Z

Many SLC NANDs support up to 4 writes at one NAND page. Add support of this feature. Signed-off-by: Artem Bityutskiy

[MTD] [NAND] remove len/ooblen confusion.

2006-11-28T22:39:03Z

As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account. Artem, BTW, thanks a lot for your valuable input! Signed-off-by: Vitaly Wool Signed-off-by: David Woodhouse

[MTD] NAND Expose the new raw mode function and status info to userspace

2006-05-29T22:37:34Z

The raw read/write access to NAND (without ECC) has been changed in the NAND rework. Expose the new way - setting the file mode via ioctl - to userspace. Also allow to read out the ecc statistics information so userspace tools can see that bitflips happened and whether errors where correctable or not. Also expose the number of bad blocks for the partition, so nandwrite can check if the data fits into the parition before writing to it. Signed-off-by: Thomas Gleixner
