[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] Clarify OOB-operation interface comments

2007-02-09T15:27:50Z

Add more comment to OOB I/O interface. Read/write are not symmetric which is confusing and should be documented. Signed-off-by: Artem Bityutskiy 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] [NOR] Intel: remove ugly PROGREGION macros

2007-02-09T15:26:37Z

Remove ugly and weird MTD_PROGREGION_CTRLMODE_VALID() and MTD_PROGREGION_CTRLMODE_INVALID() macros. There is only one user of them and they are used locally just for printing. Anyway, this patch is a preparation for removing mtd->ecctype and mtd->eccsize, but these macros use them. Fix this. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

[MTD] add get and put methods

2006-11-29T15:04:53Z

This patch adds get_device() and put_device() methods to the MTD description structure (struct mtd_info). These methods are called by MTD whenever the MTD device is get or put. They are needed when the underlying driver is something smarter then just flash chip driver, for example UBI. Signed-off-by: Artem Bityutskiy

[MTD] add get_mtd_device_nm() function

2006-11-29T15:04:31Z

This patch adds one more function to the MTD interface to make it possible to open MTD devices by their names, not only numbers. This is very handy in many situations. Also, MTD device number depend on load order and may vary, while names are fixed. Signed-off-by: Artem Bityutskiy

[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: kernel-doc fixes + additions

2006-06-29T07:55:41Z

Fix some kernel-doc typos/spellos. Use kernel-doc syntax in places where it was almost used. Correct/add struct, struct field, and function param names where needed. Signed-off-by: Randy Dunlap Signed-off-by: David Woodhouse
