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. |
|
|
