i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for the rpmsg communication. Both use cases need a fixed location of memory reserved. For the rpmsg use case the reserved area needs to be in sync with the kernel's hardcoded vring descriptor location. Use the linux,usable-memory property to carve out 1MB of memory in case the M4 core is running. Also make sure that the i.MX 7 specific rpmsg driver does not get loaded in case we do not carve out memory.
