Sebastian Bøe 55ee53ce91 cmake: Prepend 'cmake_minimum_required()' into 'app' build scripts
Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.

Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.

To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.

This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.

The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

NFC Sample App
--------------

This is a simple application to test an elementary signal-through
with NFC module connected to the second UART.


Build and run
-------------

To test the serial line routines, open a terminal window and type:

	nc -l 8888

Open another terminal window and type:

For QEMU x86:
	mkdir build; cd build
	cmake -DBOARD=qemu_x86 ..
	make run

For QEMU ARM:
	mkdir build; cd build
	cmake -DBOARD=qemu_cortex_m3 ..
	make run


Sample output
-------------

Write some random text on the nc terminal window. The terminal
window running qemu must display:

For QEMU x86:

[QEMU] CPU: qemu32
Sample app running on: x86
uart1_init() done
uart1_isr: 61 73 64 73 61 64 73 0a (8 bytes)

For QEMU ARM:

[QEMU] CPU: cortex-m3
Sample app running on: arm
uart1_init() done
uart1_isr: 61 (1 bytes)
uart1_isr: 73 (1 bytes)
uart1_isr: 64 (1 bytes)
