From 10d6ac94e0aa8bbbde45094e988c87ca971e1f10 Mon Sep 17 00:00:00 2001 From: Ben Gardiner Date: Thu, 14 Oct 2010 17:26:17 -0400 Subject: [PATCH] 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'.
