From 434f2cfcad9f70231ad5a096325ba72ef0d2a2cc Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Fri, 18 Jul 2014 17:59:42 +0530 Subject: ARM: omap: move board specific NAND configs out from ti_armv7_common.h This patch moves some board specific NAND configs: - FROM: generic config file 'ti_armv7_common.h' - TO: individual board config files using these configs. So that each board can independently set the value as per its design. Following configs are affected in this patch: CONFIG_SYS_NAND_U_BOOT_OFFS: CONFIG_CMD_SPL_NAND_OFS: CONFIG_SYS_NAND_SPL_KERNEL_OFFS: CONFIG_CMD_SPL_WRITE_SIZE: This patch also updates documentation for few of above NAND configs.
