This simple driver provides some functions to control some of the integrated devices. The watchdog is enabled per default. This driver adds a function to disable the watchdog. Also the internal legacy UART (io address 0x3f8/0x2f8) is enabled per default. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Cc: Simon Glass <sjg@chromium.org>
