-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.
