[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.

+ 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".
