From: Diana Craciun <redacted> The CoreNet coherency fabric is a fabric-oriented, conectivity infrastructure that enables the implementation of coherent, multicore systems. The CCF acts as a central interconnect for cores, platform-level caches, memory subsystem, peripheral devices and I/O host bridges in the system.

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. 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. -Scott
