The CoreNet coherency fabric is a fabric-oriented, conectivity
infrastructure that enables the implementation of coherent, multicore

platform-level caches, memory subsystem, peripheral devices and I/O host
bridges in the system.

+Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding
+
+DESCRIPTION
+
+The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
+that enables the implementation of coherent, multicore systems.
+
+Required properties:
+
+- compatible : <string>
+ Must include "fsl,corenetX-cf", "fsl,corenet-cf" - CoreNet
coherency
+ fabric version X
Specify "fsl,corenet1-cf" and "fsl,corenet2-cf" rather than
"fsl,corenetX-cf" (given there's nothing in a chip manual that you can
correlate with the value of X), and provide example chips for each.
OK.
Also specify that "fsl,corenet-cf" represents the registers that are
common between the two versions (not arbitrary "fsl,corenetX-cf" -- if
there's ever an "fsl,corenet3-cf" it may not be compatible with this),
and is retained for compatibility reasons.
What do you mean by common? There are the csdids and snoop ids
registers which are common between the two versions but only by name
because the register format is not the same.
