+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 the Devicetree Specification.
+
+In addition to the the Devicetree Specification 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.
+
+ - fsl,portid-mapping
+ Usage: optional
+ Value type: <u32>
+ Definition: The Coherency Subdomain ID Port Mapping Registers and
+ Snoop ID Port Mapping registers, which are part of the CoreNet
+ Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
+ ID/CoreNet Snoop ID to cpu mapping functions. Certain bits from
+ these registers should be set if the coresponding CPU should be
+ snooped. This property defines a bitmask which selects the bit
+ that should be set if this cpu should be snooped.
