Update igep00x0 code with the following features: - Add board and revision detection for the boards: - IGEP0020-RF - IGEP0020-RC - IGEP0030-RG - IGEP0030-RE - Merge IGEP0020 and IGEP0030 mux tables - Add suport to use GPIO_126, GPIO_127 and GPIO_129 - board_name and board_rev environment variables display board and revision informations - Move dtb name selection from code to boot script Signed-off-by: Pau Pajuelo <ppajuel@gmail.com> Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Tested-by: Pau Pajuelo <ppajuel@gmail.com>
