162306a36Sopenharmony_ci* Bus Enumeration by Freescale PCI-X Agent 262306a36Sopenharmony_ci 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. 762306a36Sopenharmony_ci 862306a36Sopenharmony_ciThe property defined below will allow a PCI-X bridge to be used for bus 962306a36Sopenharmony_cienumeration despite being strapped into Agent mode. 1062306a36Sopenharmony_ci 1162306a36Sopenharmony_ciRequired properties: 1262306a36Sopenharmony_ci- fsl,pci-agent-force-enum : There is no value associated with this 1362306a36Sopenharmony_ci property. The property itself is treated as a boolean. 1462306a36Sopenharmony_ci 1562306a36Sopenharmony_ciExample: 1662306a36Sopenharmony_ci 1762306a36Sopenharmony_ci /* PCI-X bridge known to be PrPMC Monarch */ 1862306a36Sopenharmony_ci pci0: pci@ef008000 { 1962306a36Sopenharmony_ci fsl,pci-agent-force-enum; 2062306a36Sopenharmony_ci #interrupt-cells = <1>; 2162306a36Sopenharmony_ci #size-cells = <2>; 2262306a36Sopenharmony_ci #address-cells = <3>; 2362306a36Sopenharmony_ci compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci"; 2462306a36Sopenharmony_ci device_type = "pci"; 2562306a36Sopenharmony_ci ... 2662306a36Sopenharmony_ci ... 2762306a36Sopenharmony_ci }; 28
