Bug#638863: "shpchp: Cannot reserve MMIO region" error during boot (linux 3.0)

[Bjorn Helgaas <bhelgaas@google.com>]

Your error is "SP5100 TCO timer: mmio address 0xbafe00 already in
use".  (Same error, but different address.)  That looks like it's in
the middle of your RAM, i.e., it looks completely bogus.  Given the
ugliness of the sp5100_tco driver, that doesn't surprise me.  Possibly
the BIOS configured it differently and we tried to read the MMIO
address from the wrong (hard-coded) I/O ports.  If we can dig up a
spec for this device, maybe this could be fixed up.
