From 47bf4986815407393c1cf02922c882ed0f336bb2 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sun, 17 Nov 2019 02:58:00 +0100 Subject: nb/intel/sandybridge/mrc: Handle P2P disabling via devicetree Some Sandy Bridge boards disabled the PCI-to-PCI bridge early to avoid probing by the MRC. We can do that for all boards instead, based on the devicetree setting.
