ARM: OMAP: TI81XX: Prepare for addition of TI814X support
This patch updates existing macros, functions used for TI816X, to enable addition of other SoCs belonging to TI81XX family (e.g., TI814X). The approach taken is to use TI81XX/ti81xx for code/data going to be common across all TI81XX devices. cpu_is_ti81xx() is introduced to handle code common across TI81XX devices. In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved in mach-omap2/common.c as same will be used for TI814X and is not board specific.
