Subject: kirkwood_nand: allow usage of NAND_ECC_SOFT_BCH
X-Git-Tag: v2013.04-rc3~1^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7070b550bee9341bcb53ceda15f9e0a58df88140;p=platform%2Fkernel%2Fu-boot.git

kirkwood_nand: allow usage of NAND_ECC_SOFT_BCH

If CONFIG_NAND_ECC_BCH is set use 4-bit error correction code instead of
the 1-bit error correction code on the NAND device.
