| * Bus Enumeration by Freescale PCI-X Agent |
| |
| 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. |
| |
| The property defined below will allow a PCI-X bridge to be used for bus |
| enumeration despite being strapped into Agent mode. |
| |
| Required properties: |
| - fsl,pci-agent-force-enum : There is no value associated with this |
| property. The property itself is treated as a boolean. |
| |
| Example: |
| |
| /* PCI-X bridge known to be PrPMC Monarch */ |
| pci0: pci@ef008000 { |
| fsl,pci-agent-force-enum; |
| #interrupt-cells = <1>; |
| #size-cells = <2>; |
| #address-cells = <3>; |
| compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci"; |
| device_type = "pci"; |
| ... |
| ... |
| }; |
