You should be able to achieve this without any remoteproc core changes.
You can do this by defining a reserved-memory node in your DTS file (can
be a CMA pool or a DMA pool), assigning the node using memory-region in
your remoteproc DT node and using the function,
of_reserved_mem_device_init() in your remoteproc driver.
