rpmsg is a very specialized thing. It targets single AMP cores, assuming
that those have full access to the main memory. And it is also a
centralized approach where all message go through the main Linux
instance. I suspect we could cover that use case as well with generic
inter-vm shared memory device, but I didn't think about all details yet.
