Subject: nand: Remove CONFIG_MTD_NAND_VERIFY_WRITE
X-Git-Tag: v2015.04-rc5~2^2~3
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=073adf987e8251ad934fcac4fd1bf20d4f34f96e;p=oweals%2Fu-boot.git

nand: Remove CONFIG_MTD_NAND_VERIFY_WRITE

The CONFIG_MTD_NAND_VERIFY_WRITE has been removed from Linux for some
time and a more generic method of NAND verification now exists in U-Boot.
