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.
