The switch upstream ports can only be plugged into PCIe Root Ports. There is an error in the RFC showing otherwise, it is already corrected in V1, not yet upstream. What about DMI-to-PCI Bridges? Yes, the dmi-to-pci bridge can be plugged into the pxb-pcie, I'll be sure to emphasize it. Thanks, Marcel
