Hi,
I check AMD BKDG and MMCONFIG region should be marked non-posted (CPU waits for
transaction to complete). Also this suggest the PCI ENC. I think the early bar3
code sets non-posted in sb700/rs780 but in general we dont have any generic support.

It looks we have no support for posted/non-posted MMIO resource type right?
As the side note, the fam10h has MMIO MMCONFIG region too.
Most likely we should for AMDadd the NON_POSTED resource and set the bit in
resourcemap (the MMIO routing registers)
Thanks,
Rudolf
