   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.
