DaVinci: EDMA: Adding 2 new APIs for allocating/freeing PARAMs
For best performance, codecs often setup linked triggered
transfers with a contiguous block of params, and that is when
this API is used. Setup/configuration of these parameter RAMs
is most efficient if they are contiguous.
There is an API to allocate a set of contiguous parameter RAMs and
a corresponding API to free a set of contiguous parameter RAMs
