From 24d25dbfa63c376323096660bfa9ad45a08870ce Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 5 Jan 2012 14:27:19 -0700 Subject: x86/PCI: amd: factor out MMCONFIG discovery This factors out the AMD native MMCONFIG discovery so we can use it outside amd_bus.c. amd_bus.c reads AMD MSRs so it can remove the MMCONFIG area from the PCI resources. We may also need the MMCONFIG information to work around BIOS defects in the ACPI MCFG table.
