Ilya Tagunov 08418a210d drivers: uart: stm32: improve STM32L0 support
STM32L0 UARTs are named as STM32F0 ones, but their
clocking is like all other families.

Ilya Tagunov 84cffc7f29 drivers: uart: stm32: make comments and options less specific
Replace specific STM32F1 references with generic STM32 ones.
Use generic names like U(S)ARTx for instances which have different
naming across STM32 families.

Upcoming Nordic ICs that share many of the peripherals and architecture

family. In order to accomodate that, rename the SoC family from nrf5 to
nrf, so that it can contain all of the members of the wider Nordic

There are some minor differences between the UART om SAMD20 and SAMD21

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

was to "deprecate the CC3200 launchxl support in Zephyr

Effectively, the CC3220 SOC replaces the CC3200.

This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.

Also, it fixes explicit references to CC3200 in generic
