Add a reserved memory node to reserve a portion of the DDR memory to be used for performing inter-processor communication between all the MCU R5F remote processors running RTOS on all the TI AM654 boards. This memory shall be exercised only if the MCU R5FSS cluster is configured for Split mode. A single 1 MB of memory at 0xa2000000 is reserved for this purpose, and this accounts for all the vrings and vring buffers between pair of these R5F remote processors.
