This SOC_INTEL_DISABLE_IGD Kconfig will allow to skip IGD initialization using FSP GOP and eventually disable the IGD. TEST=Able to get depthcharge pre-OS splash screen when mainboard user selects SOC_INTEL_DISABLE_IGD with below HW/FW/SW configuration: HW: ADLRVP + AMD Radeon RX 5700 PCI-E DGPU FW: coreboot with depthcharge as payload for ADLRVP and OpRom for AMD PCI-E DGPU SW: Chrome OS RC10 release Change-Id: I465541cb45c9022d53a5beb3fff1f80660c357c9 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/49470 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>
