X-Git-Tag: v2008.10-rc3~15 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fecb5ade3b37f62981f2b05b621005850173aaa9;p=platform%2Fkernel%2Fu-boot.git Fix the NAND size overflow issue. When the total size of all NAND devices exceeds 4 GiB, the size will overflow. This patch tries to fix this. Note that we still have a problem when a single NAND device is bigger than 4 GiB: then the overflow would actually happen earlier, i. e. when storing the size in nand_info[].size, as nand_info[].size is an "u_int32_t".
