+===================================================================
+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.
