362306a36Sopenharmony_ciTypically any Freescale PCI-X bridge hardware strapped into Agent mode
462306a36Sopenharmony_ciis prevented from enumerating the bus. The PrPMC form-factor requires
562306a36Sopenharmony_ciall mezzanines to be PCI-X Agents, but one per system may still
662306a36Sopenharmony_cienumerate the bus.
