0001 * Bus Enumeration by Freescale PCI-X Agent
0002 
0003 Typically any Freescale PCI-X bridge hardware strapped into Agent mode
0004 is prevented from enumerating the bus. The PrPMC form-factor requires
0005 all mezzanines to be PCI-X Agents, but one per system may still
0006 enumerate the bus.
0007 
0008 The property defined below will allow a PCI-X bridge to be used for bus
0009 enumeration despite being strapped into Agent mode.
0010 
0011 Required properties:
0012 - fsl,pci-agent-force-enum : There is no value associated with this
0013   property. The property itself is treated as a boolean.
0014 
0015 Example:
0016 
0017         /* PCI-X bridge known to be PrPMC Monarch */
0018         pci0: pci@ef008000 {
0019                 fsl,pci-agent-force-enum;
0020                 #interrupt-cells = <1>;
0021                 #size-cells = <2>;
0022                 #address-cells = <3>;
0023                 compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci";
0024                 device_type = "pci";
0025                 ...
0026                 ...
0027         };
