rpmsg-echo-test example demonstrates how to write linux userspace application that uses rpmsg devices in kernel space. This application sends pre-defined payload to remote processor firmware and waits for remote processor to send same payload back. It then verifies received payload integrity. Number of packets to send to remote processor can be configured from command line

Move rpmsg-echo-test examples from meta-openamp
3e3dcf9 
examples directory will contain different apps demonstrating
various functionality of openamp framework

This particular app was moved from meta-openamp project as
meta-openamp is supposed to have only Yocto bitbake recipes and
not source files.

This app demonstrates fast IPC communication without data corruption
between Host and Remote processor. IPC communication is done via
rpmsg framework in kernelspace

Ah! I understand now. That would be: https://github.com/OpenAMP/open-amp/blob/main/apps/examples/echo/rpmsg-echo.c

I will update README accordingly in all the examples.

@arnopo , @edmooring
Could you please look at latest change ?
I can only re-request review for one of you.
I am not sure why I can't re-request reviews for both of you.
