1* Bus Enumeration by Freescale PCI-X Agent
2
3Typically any Freescale PCI-X bridge hardware strapped into Agent mode
4is prevented from enumerating the bus. The PrPMC form-factor requires
5all mezzanines to be PCI-X Agents, but one per system may still
6enumerate the bus.
7
8The property defined below will allow a PCI-X bridge to be used for bus
9enumeration despite being strapped into Agent mode.
10
11Required properties:
12- fsl,pci-agent-force-enum : There is no value associated with this
13  property. The property itself is treated as a boolean.
14
15Example:
16
17	/* PCI-X bridge known to be PrPMC Monarch */
18	pci0: pci@ef008000 {
19		fsl,pci-agent-force-enum;
20		#interrupt-cells = <1>;
21		#size-cells = <2>;
22		#address-cells = <3>;
23		compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci";
24		device_type = "pci";
25		...
26		...
27	};
