UBI on the nand works nice with this patches, so: Acked-by: Heiko Schocher This patchset replaces my patch: Patchwork [U-Boot] mxs_nand: Fix ECC strength for NAND flash with OOB size of 256 http://patchwork.ozlabs.org/patch/460462/ bye, Heiko -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany
