Torsten Rasmussen 407b49b35c cmake: use find_package to locate Zephyr 
Using find_package to locate Zephyr.

Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.

Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.

It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

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.

Building the application for lpcxpresso54114_m4
***********************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/openamp

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:
