+===================================================================
+Power Architecture CPU Binding
+Copyright 2013 Freescale Semiconductor Inc.
+
+Power Architecture CPUs in Freescale SOCs are represented in device trees as per the
+definition in ePAPR.
+
+In addition to the ePAPR definitions, the properties defined below may be present
+on CPU nodes.
+
+PROPERTIES
+
+ - fsl,eref-*
+ Usage: optional
+ Value type: <empty>
+ Definition: The EREF (EREF: A Programmer.s Reference Manual for Freescale Power Architecture)
+ defines the architecture for Freescale Power CPUs. The EREF defines some architecture categories
+ not defined by the Power ISA. For these EREF-specific categories, the existence of a property
+ named fsl,eref-[CAT], where [CAT] is the abbreviated category name with all uppercase letters
+ converted to lowercase, indicates that the category is supported by the implementation.
