rpmsg-utils provides user-space utilities for the Linux RPMsg character
driver from the OpenAMP system reference. It includes tools for managing
RPMsg communication channels with remote processors: rpmsg_export_dev,
rpmsg_export_ept, rpmsg_destroy_ept, and rpmsg_ping.

Linux userspace RPMsg echo_test demo from the OpenAMP system
reference examples. This application uses the Linux kernel RPMsg
framework to send buffers to a remote processor and verify the
echoed data.
Requires kernel headers >= 4.11 for linux/rpmsg.h.
