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: <refer doc/README.nand> CONFIG_CMD_SPL_NAND_OFS: <refer doc/README.falcon> CONFIG_SYS_NAND_SPL_KERNEL_OFFS: <refer doc/README.falcon> CONFIG_CMD_SPL_WRITE_SIZE: <refer doc/README.falcon> This patch also updates documentation for few of above NAND configs.
