116II. Watchdog support
117
118 For security reasons, the at91 watchdog is running at boot time and,
119 if deactivated, cannot be used anymore.
120 If you want to use the watchdog, you will need to keep it running in
121 your code (make sure not to disable it in AT91Bootstrap for instance).
122
123 In the U-Boot configuration, the AT91 watchdog support is enabled using
124 the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options.
