    x86/gpu: add CFL to early quirks · 33aa69ed
    Lucas De Marchi authored
    CFL was missing from intel_early_ids[]. The PCI ID needs to be there to
    allow the memory region to be stolen, otherwise we could have RAM being
    arbitrarily overwritten if for example we keep using the UEFI framebuffer,
    depending on how BIOS has set up the e820 map.
