| * [MTD] NAND: Fix ECC settings in CAFÉ controller driver.David Woodhouse2006-11-01
| | | | | | | | | | | | | | | | We were resetting cafe->ctl2 to zero after an erase (and also during a write, but it was correctly reset after that). This meant that ECC reads after an erase were failing. Doh. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* | | [MTD] [NAND] remove len/ooblen confusion.Vitaly Wool2006-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <vwool@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* | | [MTD] NAND: Fix nand_default_mark_blockbad() when flash-based BBT disabledRicard Wanderlöf2006-10-26
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a flash-based BBT is not used, nand_default_mark_blockbad() is supposed to mark the block bad in the oob. However, it sets the wrong length variable so that no bad block marker is in fact written. This patch attempts to rectify that. (As note, it seems to be that logically, it shouldn't be necessary to set both length variables, as one appears to be for the main buffer, and one for the oob buffer, but this is how it is done in several places, including the code for the mtd character device MEMWRITEOOB and MEMREADOOB ioctls. I'm not sure if this is a temporary solution during some rework of the mtd infrastructure, or whether there is a deeper thought here.)

* | [MTD] NAND: Combined oob buffer so it's contiguous with dataDavid Woodhouse2006-10-21
| | | | | | | | | | | | | | | | | | | | Ditch the separate oobrbuf and oobwbuf fields from the chip buffers, and use only a single buffer immediately after the data. This accommodates NAND controllers such as the OLPC CAFÉ chip, which can't do scatter/gather DMA so needs the OOB buffer to be contiguous with the data, for both read and write.
