Isn't the DWC ATU programmed to make sure that the PCI memory window DT
provides _is_ the PCI "bus" memory base address ?

It is a question, I don't know the DWC inner details fully.

I don't get what you mean by "I don't think so". Either the host controller
AXI<->PCI translation is programmable, then the PCI base address is what
we decide it is or it isn't.
