The first 4k region of CCSR space is well defined for local access
windows, CCSRBAR, etc.  The second 4k region is well defined as
register for configuring and getting errors for the MPX coherency
module.

+The LAW node represents the region of CCSR space where local access
+windows are configured.  For MCM based devices this is the first 4k
+of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
+number of local access windows as specified by fsl,num-laws.

Am I right in thinking that this patch doesn't (as yet) enable any added 
functionality, or have I missed something?

I assume this is destined for next (as it relies on Becky's 
"powerpc/86xx: Add 36-bit device tree for mpc8641hpcn"), assuming this, 
fwiw, seems good to me.
