Subject: spl: nand: sunxi: stop guessing the redundant u-boot offset
X-Git-Tag: v2016.07-rc2~2^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fa3011587887ba222bc9337d9ac17f3000db63b2;p=platform%2Fkernel%2Fu-boot.git

spl: nand: sunxi: stop guessing the redundant u-boot offset

Use CONFIG_SYS_NAND_U_BOOT_OFFS_REDUND value instead of trying to guess
where the redundant u-boot image is based on simple (and most of the time
erroneous) heuristics.
