soc/amd/cezanne: add empty ramstage FCH support Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I38c6961b65b89cb57ff80e491bf8973be4e12eeb Reviewed-on: https://review.coreboot.org/c/coreboot/+/50094 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Raul Rangel <rrangel@chromium.org>

soc/amd/cezanne/fch: add ACPI I/O port setup The offsets of ACPI_CPU_CONTROL and ACPI_GPE0_BLK match the ones from the reference code, but not the PPR. I've submitted a change request for the PPR, so this mismatch might go away in the future. The case for HAVE_SMI_HANDLER will be implemented in a future patch. If that one ends up being identical to the function in soc/amd/picasso, I'll move it to the common AMD SoC code.
