- =====================================================================
- Local Access Window (LAW) Node
- The LAW node represents the region of CCSR space where local access
- windows are configured. For ECM based devices this is the first 4k
- of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
- number of local access windows as specified by fsl,num-laws.
- PROPERTIES
- - compatible
- Usage: required
- Value type: <string>
- Definition: Must include "fsl,ecm-law"
- - reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A standard property. The value specifies the
- physical address offset and length of the CCSR space
- registers.
- - fsl,num-laws
- Usage: required
- Value type: <u32>
- Definition: The value specifies the number of local access
- windows for this device.

- E500 Coherency Module Node
- The E500 LAW node represents the region of CCSR space where ECM config
- and error reporting registers exist, this is the second 4k (0x1000)
- of CCSR space.
- PROPERTIES
- - compatible
- Usage: required
- Value type: <string>
- Definition: Must include "fsl,CHIP-ecm", "fsl,ecm" where
- CHIP is the processor (mpc8572, mpc8544, etc.)
- - reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A standard property. The value specifies the
- physical address offset and length of the CCSR space
- registers.
- - interrupts
- Usage: required
- Value type: <prop-encoded-array>
- - interrupt-parent
- Usage: required
- Value type: <phandle>
