| 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. |
