MTD/JFFS2: remove CVS keywords

2008-06-04T16:50:17+00:00

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This patch therefore removes all usages of the no longer updated CVS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.

[MTD] fix mtdconcat for subpage-write NAND

2007-10-14T12:38:02+00:00

This allows the mtdconcat driver to work with NAND flash devices that
support sub-page writes.

[MTD] [NAND] make oobavail public

2007-03-08T09:17:43+00:00

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.

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

2007-02-09T15:27:12+00:00

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.

[MTD] NAND: add subpage write support

2006-11-29T15:03:52+00:00

Many SLC NANDs support up to 4 writes at one NAND page. Add support
of this feature.

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

2006-11-28T22:39:03+00:00

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!

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

2006-05-29T22:37:34+00:00

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.
