OpenAMP Sample Application
##########################
Overview
********
This application demonstrates how to use OpenAMP with Zephyr. It is designed to
demonstrate how to integrate OpenAMP with Zephyr both from a build perspective
and code. Note that the remote and primary core images can be flashed
independently, but sysbuild must be used in order to flash them in one step.

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Reset the board and the following message will appear on the corresponding
serial port, one is master another is remote:
