+          Select the default watchdog timer period to be used by the PowerPC
+          Book-E watchdog driver.  A watchdog "event" occurs when the bit
+          position represented by this number transitions from zero to one.
+
+          For Freescale Book-E processors, this is a number between 0 and 63.
+          For other Book-E processors, this is a number between 0 and 3.
+
+          The value can be overidden by the wdt_period command-line parameter.
