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