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.
2022-09-13 23:14:27 +05:00
In addition to the Devicetree Specification definitions, the properties
2022-04-02 18:12:00 +05:00
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.
