+	  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.
