What kind of segment information? Attached is a preview of information that I supply to instances of pci(4), ppb(4), and cbb(4) through their device properties. The information will help them manage PCI address spaces and to program their address windows correctly, so that I can retire rbus and PCI_ADDR_FIXUP, whose heuristics are incomplete. Currently, I derive the information by scanning PCI Configuration Space. The system BIOS---be it OpenFirmware, ACPI, or something else---may supply similar information.
