	  The SPS (Smart Peripheral Switch) is a DMA engine.

	  It can move data in the following modes:

		1. Peripheral-to-Peripheral.

		2. Peripheral-to-Memory.

		3. Memory-to-Memory.

	help

	  The BAM-DMA is used for Memory-to-Memory transfers.

	  The main use cases is RPC between processors.

	  The BAM-DMA hardware has 2 registers sets:

		1. A BAM HW like all the peripherals.

		2. A DMA channel configuration (i.e. channel priority).

	help

	  No-Data-Path BAM is used to improve BAM performance.

	  NDP BAMs enables peripherals with fast fabric connectivity

	  to do the actual data transfer themselves, instead of the

	  BAM.
