Data cache alignment. If any side of the communication uses cache on
|
|
rx-region/tx-region this property must be the biggest value of the
|
|
invalidation or the write-back size for both sides of the communication.
|
|
If no side of the communication uses data cache this property could be
|
|
safely omitted.
|
|
For example:
|
|
Side A: no data cache
|
|
Side B: 32 Bytes write-back size, 16 Bytes invalidation size
|
|
dcache-alignment = 32; for both
