0005 
0006 Local Access Window (LAW) Node
0007 
0008 The LAW node represents the region of CCSR space where local access
0009 windows are configured.  For ECM based devices this is the first 4k
0010 of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
0011 number of local access windows as specified by fsl,num-laws.

0013 PROPERTIES
0014 
0015   - compatible
0016       Usage: required
0017       Value type: <string>
0018       Definition: Must include "fsl,ecm-law"
0019 
0020   - reg
0021       Usage: required
0022       Value type: <prop-encoded-array>
0023       Definition: A standard property.  The value specifies the
0024           physical address offset and length of the CCSR space
0025           registers.

0035 E500 Coherency Module Node
0036 
0037 The E500 LAW node represents the region of CCSR space where ECM config
0038 and error reporting registers exist, this is the second 4k (0x1000)
0039 of CCSR space.
