cfi: fix the incomplete erased status check in buffer write

2012-03-21T15:25:33Z

Without the fix, flash_write_cfibuffer will terminate the erased status check once an all-0xFF word has been found instead of continuing the erased status check utill the first non-0xFF word. Signed-off-by: Tao Hou Cc: Stefan Roese Signed-off-by: Stefan Roese

mtd/nand:Fix wrong usage of is_blank() in fsl_ifc_run_command

2012-02-28T20:03:39Z

Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in fsl_ifc_run_command() during ECC status verification. Also this sector is passed to is_blank() for blank checking. It is wrong at first place because is_blank()'s implementation checks for Page size and OOB area size. is_blank() should be called per page for main and OOB area verification. Variables name are redefined to avoid confusion between buffer and ecc sector. Signed-off-by: Poonam Aggrwal Signed-off-by: Prabhakar Kushwaha Signed-off-by: Scott Wood

mtd/nand: Fix IFC driver to support 2K NAND page

2012-02-28T20:03:39Z

1) OOB area should be updated irrespective of NAND page size. Earlier it was updated only for 512byte NAND page. 2) During OOB update fbcr should be equal to OOB size. Signed-off-by: Poonam Aggrwal Signed-off-by: Prabhakar Kushwaha Signed-off-by: Scott Wood

nand: reinstate lazy bad block scanning

2012-02-28T20:03:39Z

commit 2a8e0fc8b3dc31a3c571e439fbf04b882c8986be ("nand: Merge changes from Linux nand driver") accidentally reverted commit 13f0fd94e3cae6f8a0d9fba5d367e311edc8ebde ("NAND: Scan bad blocks lazily."). Reinstate the change, as amended by commit ff49ea8977b56916edd5b1766d9939010e30b181 ("NAND: Mark the BBT as scanned prior to calling scan_bbt."). Signed-off-by: Scott Wood

Revert "nand: make 1-bit software ECC configurable"

2012-02-28T20:03:39Z

This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5. It breaks boards that currently rely on soft-ecc, as pointed out here: http://patchwork.ozlabs.org/patch/140872/ The reverted patch should be resubmitted with documentation, and with the CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could start by looking at what NAND driver the board selects, and whether that driver ever asks for soft ECC. Signed-off-by: Scott Wood

Merge branch 'sf' of git://git.denx.de/u-boot-blackfin

* 'sf' of git://git.denx.de/u-boot-blackfin: README: Add description of SPI Flash (SF) command configuration sf command: allow default bus and chip selects sf: eeprom_m95xxx: set a sane default timeout sf: eeprom_m95xxx: fix up style

sf: eeprom_m95xxx: set a sane default timeout

2012-02-12T20:18:28Z

Every board currently defines this to the same value, so just default to that to avoid having to make everyone do the same thing. Signed-off-by: Mike Frysinger
