Hi Ranga,
Trying to figure out how the GOP driver is enabled/added in the coreboot tree.
IntelGraphicsPeim.efi IntelGopDriver.efi
Above 2 drivers part of FSP?
IntelGraphicsPeim.efi is included in the FSP. For the DXE GOP driver you have to integrate it into your final solution, e.g. tianocore payload (and additionally provide GOP policy protocol).
To use the graphics PEIM, include your VBT in CBFS and in the coreboot menuconfig select: Devices -> Graphics Initialization -> Run GOP driver VBT can be included in the Device submenu.
Best regards,
