From 4b94f1dc874af4c851db28b70a0e0330748f2f08 Mon Sep 17 00:00:00 2001 From: Jon Murphy Date: Thu, 6 Apr 2023 10:17:25 -0600 Subject: mb/google/myst: 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. Enable the mp2 device in the mainboard's devicetree so that it gets its resources assigned by coreboot.
