[Sandeep]: Looks like you are building for cortex-a processor. rpmsg 
works for only these platforms 
https://github.com/OpenAMP/openamp-system-reference/blob/main/examples/zephyr/rpmsg_multi_services/sample.yaml#L8-L10 
I used "MACHINE=qemu-cortex-r5 bitbake zephyr-openamp-rpmsg-multi-srv" 
to test this recipe.,this way we can avoid the issues. I can add a 
machine compatible for only these available machines. I will send a v2 
patch.
