watchdog: Add TCO support for nVidia chipsets
This driver adds support for /dev/watchdog for boards using either the MCP51 or MCP55 chipsets. These are also known as the nForce 430 and nForce 550. This driver is likely to work on other chipsets as well, though those are the only two that have been tested.

648 ---help---
649 Hardware driver for the TCO timer built into the nVidia Hub family
650 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
651 watchdog timer that will reboot the machine after its second
652 expiration. The expiration time can be configured with the
653 "heartbeat" parameter.
654
655 On some motherboards the driver may fail to reset the chipset's
656 NO_REBOOT flag which prevents the watchdog from rebooting the
657 machine. If this is the case you will get a kernel message like
658 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

660 To compile this driver as a module, choose M here: the
661 module will be called nv_tco.
