166III. Watchdog support
Jean-Christophe PLAGNIOL-VILLARD843a2652009-03-27 23:26:42 +0100167
168 For security reasons, the at91 watchdog is running at boot time and,
169 if deactivated, cannot be used anymore.
170 If you want to use the watchdog, you will need to keep it running in
171 your code (make sure not to disable it in AT91Bootstrap for instance).
172
173 In the U-Boot configuration, the AT91 watchdog support is enabled using
Prasanthi Chellakumar1473f6a2018-10-09 11:46:40 -0700174 the CONFIG_WDT and CONFIG_WDT_AT91 options.
