From: Ben Gardiner Date: Thu, 14 Oct 2010 21:26:17 +0000 (-0400) Subject: davinci_nand, trivial : use symbolic ECC start command X-Git-Tag: v2010.12-rc1~104^2~6 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=10d6ac94e0aa8bbbde45094e988c87ca971e1f10;p=oweals%2Fu-boot.git davinci_nand, trivial : use symbolic ECC start command The ECC calculations were started by writing 1 << 13 to the nand FCR register; that value is also defined as DAVINCI_NANDFCR_4BIT_CALC_START in emif_defs.h. This patch substitutes the macro DAVINCI_NANDFCR_4BIT_CALC_START for the magic number '1 << 13'.
