From a14901804b6d46e6e05932d6dc9901c5208853b5 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Thu, 1 Dec 2022 18:51:49 +0100 Subject: mb/google/skyrim/baseboard/devicetree: enable mp2 device The mp2 PCI device is still present when no mp2 firmware is loaded. When this device isn't explicitly enabled in the mainboard's devicetree, the chipset devicetree default of the device being disabled is used. This results in coreboot's resource allocator not allocating resources to the device and since the bridge doesn't have enough MMIO space reserved, the Linux kernel can't assign resources to it. To fix this problem, enable the mp2 device in the mainboard's devicetree so that it gets its resources assigned by coreboot. An equivalent change was verified on Chausie.
