Changed paths: M lib/remoteproc/remoteproc_virtio.c M lib/rpmsg/rpmsg_virtio.c

Log Message: ----------- rpmsg_virtio.c: wait_remote_ready use sleep instead to avoid starvation

metal_cpu_yield can either result in an unimplemented function or a yield function. The yield function however only yields execution to another thread of the same or higher priority. Thus starving any lower priority threads.

wait_remote_ready can be blocked for a long time i.e. seconds waiting on the remote core to start communication.

Instead use metal_sleep_usec, allowing lower priority tasks to be executed. While waiting on the remote core.
