Michael Hope cd92dd139b flash: add a driver for the internal flash on the SAM0 series.
The SAM0 has a 64 byte page (the programing unit) with 4 pages to a
row (the erase unit).  This driver implements a read/modify/write to
emulate the byte level writes used by NFFS.

Carles Cufi 7d764b35f3 cmake: Use path-corrected version of ZEPHYR_BASE
Instead of accessing the environment variable ZEPHYR_BASE every time we
require accessing the source code root, use an intermediate variable
that has OS path separators correctly set to '/' to avoid issues on
Windows.

Note: This removes the ZEPHYR_SOURCE_DIR CMake variable. External
applications using that will need to change to use the new ZEPHYR_BASE
variable.

Neil Armstrong 32cb3f0220 flash: stm32: add support for STM32F0 flash controller
Add the STM32F0 Embedded Flash support in the flash_stm32 driver
interface.
The STM32F0 has a particularity or use the HSI as clock source
for the flash controller interface, so this clock must be
enabled directly in the case HSE or another clock is used by
the system clock.

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make
