1. rpmsg DMA library (meta-ti-bsp/recipes-ti/ipc):
	based on rpmsg & DMA Heap buffers. this includes librpmsg_dma.so shared library
	which provides apis for
		1. rpmsg interface initialization
		2. rpmsg based recv/send api for communication
		3. dma heap buffer management
		4. DSP firmware synamin load/unload

2. rpmsg DMA offload example (meta-ti-extras/recipes-ti/ipc):
	provides example foraudio offloading to DSP from linux using
	ti-rpmsg-dma library. Alsove provide Ethernet based control
	utility (host).
