Subject: Regression:  2.6.34 boot fails on E5405 system, bisected:  de08e2c26

We're seeing boot failures on multiple machines, running FC8 and
F11.  I bisected on an FC8 32-bit system.  Newer hardware works,
but these older ones do not.

A console log of the hang is found later in this email.

Please let me know if you would like any additional information,
and I will be happy to test patches.

The same failure happens in 2.6.34.1, so the fix does not appear to
be in the stable tree yet.

     x86/PCI: Moorestown PCI support

     The Moorestown platform only has a few devices that actually support
     PCI config cycles.  The rest of the devices use an in-RAM MCFG space
     for the purposes of device enumeration and initialization.

     There are a few uglies in the fake support, like BAR sizes that aren't
     a power of two, sizing detection, and writes to the real devices, but
     other than that it's pretty straightforward.

     Another way to think of this is not really as PCI at all, but just a
     table in RAM describing which devices are present, their capabilities
     and their offsets in MMIO space.  This could have been done with a
     special new firmware table on this platform, but given that we do have
     some real PCI devices too, simply describing things in an MCFG type
     space was pretty simple.
