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.
|
||
|
|
|
||
|
|
- 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.
