On the pi400, the xhci reset firmware mailbox request assumes that the pci windows match the ones specified in the device tree. The inbound window (pcidmawin) also varies now depending on the amount of memory installed. It is all pretty ridiculous, as the firmware could as well just read the pci controllers hardware register to determine the window configuration and the os could keep a nice simple 1:1 mapping (with pci dma addresses == physical addresses).
