| 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. | ||
