    6 Local Access Window (LAW) Node
    7 
    8 The LAW node represents the region of CCSR space where local access
    9 windows are configured.  For MCM based devices this is the first 4k
   10 of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
   11 number of local access windows as specified by fsl,num-laws.

   35 MPX Coherency Module Node
   36 
   37 The MPX LAW node represents the region of CCSR space where MCM config
   38 and error reporting registers exist, this is the second 4k (0x1000)
   39 of CCSR space.
