fef775ca - nand: omap2: Add support for flash-based bad block table

Thu, 11 Sep 2014 15:02:08 +0000

nand: omap2: Add support for flash-based bad block tableThis commit adds a new platform-data boolean property that enables useof a flash-based bad block table. This can also be enabled by settingthe 'nand-on-flash-bbt' devicetree property.If the flash BBT is not enabled, the driver falls back to use OOBbad block markers only, as before. If the flash BBT is enabled thekernel will keep track of bad blocks using a BBT, in addition tothe OOB markers.As explained by Brian Norris the reasons for using a BBT are:""The primary reason would be that NAND datasheets specify it these days.A better argument is that nobody guarantees that you can write abad block marker to a worn out block; you may just get program failures.This has been acknowledged by several developers over the last severalyears.Additionally, you get a boot-time performance improvement if you onlyhave to read a few pages, instead of a page or two from every block onthe flash.""Signed-off-by: Ezequiel Garcia Acked-by: Roger Quadros Signed-off-by: Brian Norris List of files: /linux-6.15/include/linux/platform_data/mtd-nand-omap2.h

7d5929c1 - mtd: nand: omap: Revert to using software ECC by default

Mon, 25 Aug 2014 23:15:32 +0000

mtd: nand: omap: Revert to using software ECC by defaultFor v3.12 and prior, 1-bit Hamming code ECC via software was thedefault choice. Commit c66d039197e4 in v3.13 changed the behaviourto use 1-bit Hamming code via Hardware using a different ECC layouti.e. (ROM code layout) than what is used by software ECC.This ECC layout change causes NAND filesystems created in v3.12and prior to be unusable in v3.13 and later. So revert back tousing software ECC by default if an ECC scheme is not explicitelyspecified.This defect can be observed on the following boards during legacy boot-omap3beagle-omap3touchbook-overo-am3517crane-devkit8000-ldp-3430sdpSigned-off-by: Roger Quadros Tested-by: Grazvydas Ignotas Signed-off-by: Tony Lindgren List of files: /linux-6.15/include/linux/platform_data/mtd-nand-omap2.h
