Is there a DMA controller on the i.MX8QM that can move data between main memory and a peripheral while simultaneously snooping the cache when moving from memory to peripheral and/or creating new cache entries when moving from peripheral to main memory?
Some of the older QorIQ PowerPC processors had this feature and it sped up our application a great deal and I am hoping there is an equivalent for the i.MX8QM.

i.MX8 has no such mechanism. Sorry for the inconvenience.
