| 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 ECM 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. |

| 13 | PROPERTIES |
| 14 | |
| 15 | - compatible |
| 16 | Usage: required |
| 17 | Value type: <string> |
| 18 | Definition: Must include "fsl,ecm-law" |
| 19 | |
| 20 | - reg |
| 21 | Usage: required |
| 22 | Value type: <prop-encoded-array> |
| 23 | Definition: A standard property. The value specifies the |
| 24 | physical address offset and length of the CCSR space |
| 25 | registers. |
| 26 | |
| 27 | - fsl,num-laws |
| 28 | Usage: required |
| 29 | Value type: <u32> |
| 30 | Definition: The value specifies the number of local access |
| 31 | windows for this device. |

| 35 | E500 Coherency Module Node |
| 36 | |
| 37 | The E500 LAW node represents the region of CCSR space where ECM config |
| 38 | and error reporting registers exist, this is the second 4k (0x1000) |
| 39 | of CCSR space. |
| 40 | |
| 41 | PROPERTIES |
| 42 | |
| 43 | - compatible |
| 44 | Usage: required |
| 45 | Value type: <string> |
| 46 | Definition: Must include "fsl,CHIP-ecm", "fsl,ecm" where |
| 47 | CHIP is the processor (mpc8572, mpc8544, etc.) |
| 48 | |
| 49 | - reg |
| 50 | Usage: required |
| 51 | Value type: <prop-encoded-array> |
| 52 | Definition: A standard property. The value specifies the |
| 53 | physical address offset and length of the CCSR space |
| 54 | registers. |
