-* 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>;

+      This allows for some segmentation, e.g., one peripheral is accessible
+      through BAR0 and another through BAR1, and you don't want the two
+      peripherals to be able to act on the other BAR. Alternatively, when
+      different peripherals need to share BARs, you can define only one node
+      and use a 'ranges' property to map all the used BARs.
