Reto Schneider 7eabab2f5d samples, tests: Use semi-accurate project names When using an IDE (e.g. Eclipse, Qt Creator), the project name gets displayed. This greatly simplifies the navigation between projects when having many of them open at the same time. Naming every project "NONE" defeats this functionality. This patch tries to use sensible project names while not duplicating too much of what is already represented in the path. This is done by using the name of the directory the relevant CMakeLists.txt file is stored in. To ensure unique project names in the samples (and again, in the tests folder) folder, small manual adjustments have been done.

Protection tests
#################################

Overview
********
This test case verifies that protection is provided
against the following security issues:

* Write to read-only data.
* Write to text.
* Execute from data.
* Execute from stack.
* Execute from heap.

Building and Running
********************

This project can be built and executed as follows:


.. zephyr-app-commands::
   :zephyr-app: tests/kernel/mem_protect/protection
   :board: <board name>
   :goals: run
   :compact:

Connect the board to your host computer using the USB port.
Flash the generated zephyr.bin on the board.
Reset the board.

Sample Output
