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.
