PCI memory should be disabled at reset, otherwise we might claim transactions at address 0. I/O should also be disabled, although for cirrus it is harmless to enable it as we do not have I/O bar.
Note: need bios fix for this patch to work: currently pc-bios incorrently assumes that it does not need to enable i/o unless device has i/o bar. Signed-off-by: Michael S.
