From 35a6ae07c663499875309f18730f3440bb59f6fe Mon Sep 17 00:00:00 2001 From: Adrian-Ken Rueegsegger Date: Wed, 23 Mar 2016 11:34:29 +0100 Subject: x86/PCI: Refine PCI support check in pcibios_init() Also consider raw_pci_ext_ops when validating if a system has PCI support. This leads to proper resource allocation via pcibios_resource_survey() in the case where PCI config space is exclusively accessed through MMCONFIG.
