What are the reasons/motivation for this change?
The aim is to add a way to prevent memory that has never been written/initialised by the design itself, but might be initialised by the external (CPU/DMA writing to the memory directly in a SoC system).
Explain how this is achieved.
A new flag is added for the
memorypass andopt_mempass. At the stage of removing lanes, if the flag is presented, it will add the lane toswizzleand preserve the lane.
