56    description:
57      Typically any Freescale PCI-X bridge hardware strapped into Agent mode is
58      prevented from enumerating the bus. The PrPMC form-factor requires all
59      mezzanines to be PCI-X Agents, but one per system may still enumerate the
60      bus.
61
62      This property allows a PCI-X bridge to be used for bus enumeration
63      despite being strapped into Agent mode.
