2020-11-20soc/intel/xeon_sp: Set coreboot defined IOAPIC and HPET BDFArthur Heymans
Don't rely on the FSP-S setting the HPET and IOAPIC BDF. This makes coreboot in control of these settings.

2020-06-02soc/intel/xeon_sp: Early programming of ACPI barRocky Phagura
ACPI bar was not programmed previously for which is needed to enable SMI's and to check SMI status registers. The architecture of Lewisburg PCH is very similar to SunrisePoint PCH thus we can use code from soc/intel/skylake. TEST=build for Tiogapass and check ACPI base. Log message will now show pmbase=501 (bit 0 is enable) instead of 0. Check by reading and writing to io port 0x500.
