commit 478ab87326cc75a34c93735c8f9671c5d3adb1fc Author: Aaron Durbin adurbin@chromium.org Date: Wed Oct 31 23:05:25 2012 -0500
haswell: remove explicit pcie config accesses
Now that MMCONF_SUPPORT_DEFAULT is enabled by default remove the pcie explicit accesses. The default config accesses use MMIO.
