This patch adds a custom U-Boot command "wdogtoggle" which enables the external hardware watchdog toggling via an GPIO pin on the a4m2k board. After issuing this commands, the watchdog will be serviced by U-Boot so that the user can use all U-Boot commands from the prompt. Signed-off-by: Stefan Roese <sr@denx.de>
