Write _ROM method and store PCI Option ROM in CBMEM. Allows an EFI compatible OS to retrieve the Option ROM without the need to access the PCI BAR. As the Option ROM is no longer present in the legacy VGA area it's required for mobile platforms. On hybrid devices, like Lenovo Thinkpads supporting NVIDIA Optimus it's the only way to retrieve the Option ROM, even with legacy BIOS, as there's no PCI BAR to map. Tested on: * Lenovo T530 * Linux Kernel 4.13.7 * nouveau Change-Id: I548b730fb64833083cc05af5b21dd6959804224b Signed-off-by: Patrick Rudolph <siro@das-labor.org> Reviewed-on: https://review.coreboot.org/20548 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> |
