* [MTD] [NAND] CM-x270 MTD driverMike Rapoport2007-04-273-0/+273
| | | | | | | This patch provides MTD support for NAND flash devices on CM-x270 modules. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] [NAND] Wrong calculation of page number in nand_block_bad()Knobloch, Thomas2007-04-271-1/+1
| | | | | | | | | | | In case that there is no memory based bad block table available the function nand_block_checkbad() in drivers/mtd/nand/nand_base.c will call nand_block_bad() directly. When parameter 'getchip' is set to zero, nand_block_bad() will not right shift the offset to calculate the correct page number.

* [MTD] nandsim: enhance nandsim to allow arbitrary NAND sizeAdrian Hunter2007-04-171-1/+20
| | | | | | | | | | | | A new module parameter has been added called 'overridesize', which overrides the size that would be determined by the ID bytes. 'overridesize' is specified in erase blocks and as the exponent of a power of two e.g. 5 means a size of 32 erase blocks.

* [MTD] [NAND] Casting bug in nand_default_block_markbadAndre Renaud2007-04-171-1/+1
| | | | | | | | | | | There is a slight bug in nand_default_block_markbad, where the offset is cast to an integer, prior to being shifted. This means that on large offsets, it is incorrectly doing a signed shift & losing bits. Fixed this by doing the cast after the shift (as is done elsewhere in the code).

* [MTD] [NAND] Move ancient NAND chip support into a config optionThomas Gleixner2007-04-172-0/+12

* [MTD] [NAND] make oobavail publicVitaly Wool2007-03-081-0/+1
| | | | | | | | | | | 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 <vwool@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
