II. Watchdog support
For security reasons, the at91 watchdog is running at boot time and,
if deactivated, cannot be used anymore.
If you want to use the watchdog, you will need to keep it running in
your code (make sure not to disable it in AT91Bootstrap for instance).
In the U-Boot configuration, the AT91 watchdog support is enabled using
the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options.
