0006 Local Access Window (LAW) Node
0007
0008 The LAW node represents the region of CCSR space where local access
0009 windows are configured. For MCM based devices this is the first 4k
0010 of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
0011 number of local access windows as specified by fsl,num-laws.
