+		  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 pamu mapping
+		  functions.  Certain bits from these registers should be
+		  set if PAMUs should be snooped.  This property defines
+		  a bitmask which selects the bits that should be set if
+		  PAMUs should be snooped.
