PS7, Line 92: params->Enable8254ClockGating = 0; In change https://review.coreboot.org/c/coreboot/+/33512 it was fixed on cannonlake. Making use of CONFIG_USE_LEGACY_8254_TIMER seems fine, as it can be selected by PAYLOAD_SEABIOS or VGA_ROM_RUN. Also there's no need to have a dependency to disabled IGD. One might run dGPU oprom even with IGD enabled.
