soc/intel/skylake: Prevent disabling of TCO
In Skylake/Kabylake, if ACPI PM timer is disabled then TCO also gets disabled & vice versa. FSP default config for EnableTcoTimer is disabled, this caused ACPI PM timer & TCO to be disabled by FSP even when config PmTimerDisable = 0. Thus update FSPS UPD EnableTcoTimer in accordance to devicetree config PmTimerDisable. BUG=None TEST= Build for Soraka with PmTimerDisable=0 & check if TCO caused reboot after running shell command: cat >> /dev/watchdog0 Change-Id: Ia146761036c9dbaef3c02c9a7122ae3dcdef7bdd Signed-off-by: Naresh G Solanki <naresh.solanki@intel.com> Reviewed-on: https://review.coreboot.org/29108 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-by: Rizwan Qureshi <rizwan.qureshi@intel.com>
