Provide u-boot console functions to access IO space registers. A no thrills implementation, accessing one register at a time. For example: boot > iod 80 0080: 00000094 boot > iod.w 80 0080: 0094 boot > iod.b 80 0080: 94 boot > iow.b 0x80 12 boot > iod 0x80 0080: 00000012 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
