Hi, In Linux v3.12 and earlier some boards [1] used Software based ECC as the NAND ECC scheme. In 3.13 commit c66d039197e4 changed that to Hardware ECC using ROM code ECC layout. This will cause NAND filesystems created in 3.12 and earlier to be unreadable in v3.13 and later till they are erased and re-created. This series fixes this issue by using Software ECC as the default ECC scheme for the affected boards. Tested on omap3beagle.
