From 270a32370d92bc283ad17a58ccc1c1f0398a6915 Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Sat, 25 Jul 2020 10:49:44 +0200 Subject: soc/intel/skylake: Map VBIOS IDs The extracted VBIOS Option ROM ships the same ID for several generations, not matching the ID on the hardware resulting in a mismatch, and coreboot does not run the Option ROM. PCI ROM image, vendor ID 8086, device ID 0406, ID mismatch: vendor ID 8086, device ID 5916 Add the appropriate mappings. TEST=coreboot runs the ROM on the TUXEDO Book BU1406.
