    description:
      Typically any Freescale PCI-X bridge hardware strapped into Agent mode is
      prevented from enumerating the bus. The PrPMC form-factor requires all
      mezzanines to be PCI-X Agents, but one per system may still enumerate the
      bus.

      This property allows a PCI-X bridge to be used for bus enumeration
      despite being strapped into Agent mode.
