Erwan Gouriou 222bc6096b drivers: serial: stm32: report only unmasked irq
Fix #5298
irq_is_pending function returned TXE/RXNE flag status
even if IRQ was masked, which led to enless loop
in uart_pipe when no TX was performed. Fix by reporting status only when
IRQ is unmasked.

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

Gil Pitney 4f67a6c76d cc3200: Remove TI cc3200 SOC and LaunchXL board support
Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."

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
CC32xx driver files.

Inaky Perez-Gonzalez 271c518ec6 uart_esp32: alter the uart.h include order to avoid warning
The esp-idf package contains on the BSP a definition of the BIT macro
unconditionally #defined when rom/uart.h is #included. When Zephyr's
uart.h (which pulls in include/misc/util.h) that conditionally

This generates a compile warning on the re-definiton of BIT by the
esp-idf package.

Thus include uart.h after esp-idf's rom/uart.h to have BIT not
re-defined thanks to Zephyr's conditional definition.
