+Copyright (C) 2009 Freescale Semiconductor Inc.
+=====================================================================
+
+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.
