PS2: 
can you please rebase this CL on top of https://review.coreboot.org/c/coreboot/+/69685 to avoid the power penalty?

PS1, Line 362: 	s_cfg->EnableTcoTimer = 1;
NOTE: This will have huge power impact when it's enabled. If TCO timer is disabled, uCode ACPI timer emulation must be enabled, and WDAT table must not be exposed to the OS.
