No clue about "pxb-pcie", but re: "pxb", the documentation and examples by Marcel (see: "docs/pci_expander_bridge.txt") will certainly continue working, with this patch place. And, that text file is authoritative for pxb, since Marcel (et al) wrote the code directly for the purposes described in the txt. (But I'll let Marcel answer too! :)) Thanks Laszlo
