This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.
