[WATCHDOG] iTCO_wdt (Intel TCO Timer) driver 



Hardware driver for the intel TCO timer based watchdog devices.
These drivers are included in the Intel 82801 I/O Controller
Hub family (from ICH0 up to ICH7) and in the Intel 6300ESB
controller hub.

This driver will replace the i8xx_tco.c driver.

	  Hardware driver for the intel TCO timer based watchdog devices.

	  These drivers are included in the Intel 82801 I/O Controller

	  Hub family 'from ICH0 up to ICH7) and in the Intel 6300ESB

	  controller hub.



	  The TCO (Total Cost of Ownership) timer is a watchdog timer

	  that will reboot the machine after its second expiration. The

	  expiration time can be configured with the "heartbeat" parameter.



	  On some motherboards the driver may fail to reset the chipset's

	  NO_REBOOT flag which prevents the watchdog from rebooting the

	  machine. If this is the case you will get a kernel message like

	  "failed to reset NO_REBOOT flag, reboot disabled by hardware".



	  To compile this driver as a module, choose M here: the

	  module will be called iTCO_wdt.
