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:
  Definition: Must include “fsl,ecm-law”

• reg
  Usage: required
  Value type:
  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:
  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:
  Definition: Must include “fsl,CHIP-ecm”, “fsl,ecm” where
  CHIP is the processor (mpc8572, mpc8544, etc.)

• reg
  Usage: required
  Value type:
  Definition: A standard property. The value specifies the

    physical address offset and length of the CCSR space
    registers.
