6a24f34e5c tco: add trace events
Add trace events to the PCH watchdog timer, it can be useful to see how
the guest is using it.

8c9f42f3cf tco: do not generate an NMI
This behavior is not indicated in the datasheet and can confuse the OS.
The TCO can trap NMIs from SERR# or IOCHK# and convert them to SMIs; but
any other TCO event is either delivered as an SMI or completely disabled.

5add35bec1 ich9: implement strap SPKR pin logic
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).

The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".

This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

920557971b ich9: add TCO interface emulation
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.
