+       GETSUPPORT returns the watchdog_info struct, and
+       GETSTATUS returns the supported options. GETBOOTSTATUS
+       returns a 1 if the last reset was caused by the
+       watchdog and a 0 otherwise. This watchdog can not be
+       disabled once it has been started. The wdt_period kernel
+       parameter selects which bit of the time base changing
+       from 0->1 will trigger the watchdog exception. Changing
+       the timeout from the ioctl calls will change the
+       wdt_period as defined above. Finally if you would like to
+       replace the default Watchdog Handler you can implement the
+       WatchdogHandler() function in your own code.
