From 43b29cf891c78a2cd01d22a2731c7da828d79e0a Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Fri, 6 Mar 2009 19:11:52 +0000 Subject: Fix mmconf (PCIe memory mapped config space access) support in v2. It was horribly broken and thus never used by any platform. This needs to get straightened out so current chipsets drivers can use the full feature set. Create wrapper functions similar to the io pci config space ones.
