1662306a36Sopenharmony_ci        Definition: The EREF (EREF: A Programmer.s Reference Manual for
1762306a36Sopenharmony_ci	Freescale Power Architecture) defines the architecture for Freescale
1862306a36Sopenharmony_ci	Power CPUs.  The EREF defines some architecture categories not defined
1962306a36Sopenharmony_ci	by the Power ISA.  For these EREF-specific categories, the existence of
2062306a36Sopenharmony_ci	a property named fsl,eref-[CAT], where [CAT] is the abbreviated category
2162306a36Sopenharmony_ci	name with all uppercase letters converted to lowercase, indicates that
2262306a36Sopenharmony_ci	the category is supported by the implementation.

2762306a36Sopenharmony_ci	Definition: The Coherency Subdomain ID Port Mapping Registers and
2862306a36Sopenharmony_ci	Snoop ID Port Mapping registers, which are part of the CoreNet
2962306a36Sopenharmony_ci	Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
3062306a36Sopenharmony_ci	ID/CoreNet Snoop ID to cpu mapping functions.  Certain bits from
3162306a36Sopenharmony_ci	these registers should be set if the corresponding CPU should be
3262306a36Sopenharmony_ci	snooped.  This property defines a bitmask which selects the bit
3362306a36Sopenharmony_ci	that should be set if this cpu should be snooped.
