I am programming BOTH the inbound ATMUs to make PPC memory available to
the root complex, AND programming outbound ATMUs to enable the PPC to bus
master to the root complex's memory space on PCIe.

I am NOT attempting to program the IWBARs - as you noted, they get
programmed by the root complex via PCI config operations.

No, I am NOT confusing the two - that is why I am being VERY EXPLICIT
about accessing the OUTBOUND ATMUs.

The only reason I mention the inbound ATMUs is to demonstrate that the
physical layer is working.
