| 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. | |

| 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. | |
