From 6c705e766f7f4462da7af1817925bb6d20518d15 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 1 Nov 2023 15:52:03 -0500 Subject: mb/google/puff/var/*: Set LAN/WLAN device type to generic Change the LAN/WiFi device types from PCI to generic, so that the bogus PCI device and function values don't end up in coreboot's internal device tree. The presence of these bogus PCI devices cause the LPI constraint generator to create a reference for an ACPI device which does not exist (SB.PCI0.RP{xx}.MCHC). The invalid reference(s) cause a Windows BSOD (INTERNAL_POWER_ERROR). TEST=build/boot Win11 on google/puff (wyvern). Verify LAN/WLAN devices function correctly under Windows and Linux.
