5Power Architecture CPUs in Freescale SOCs are represented in device trees as
6per the definition in the Devicetree Specification.
7
8In addition to the the Devicetree Specification definitions, the properties
9defined below may be present on CPU nodes.

11PROPERTIES
12
13   - fsl,eref-*
14        Usage: optional
15        Value type: <empty>
16        Definition: The EREF (EREF: A Programmer.s Reference Manual for
17	Freescale Power Architecture) defines the architecture for Freescale
18	Power CPUs.  The EREF defines some architecture categories not defined
19	by the Power ISA.  For these EREF-specific categories, the existence of
20	a property named fsl,eref-[CAT], where [CAT] is the abbreviated category
21	name with all uppercase letters converted to lowercase, indicates that
22	the category is supported by the implementation.
23
24    - fsl,portid-mapping
25	Usage: optional
26	Value type: <u32>
27	Definition: The Coherency Subdomain ID Port Mapping Registers and
28	Snoop ID Port Mapping registers, which are part of the CoreNet
29	Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
30	ID/CoreNet Snoop ID to cpu mapping functions.  Certain bits from
31	these registers should be set if the coresponding CPU should be
32	snooped.  This property defines a bitmask which selects the bit
33	that should be set if this cpu should be snooped.
