From a2f40ccd294d14e5aca464c1913e8e0d8de35fca Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sat, 3 Sep 2005 15:55:33 -0700 Subject: [PATCH] ppc32: Added support for the Book-E style Watchdog Timer PowerPC 40x and Book-E processors support a watchdog timer at the processor core level. The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.
