+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.
