license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

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 PR: zephyrproject-rtos#4692 docs: http://docs.zephyrproject.org/getting_started/getting_started.html Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no>

drivers: led_strip: Add driver for software-based WS2812B operation This driver uses a bit-banging based technique of generating a signal for the WS2812B LED strip. Since bit-banging is very timing sensitive, where each CPU cycle counts, the driver uses inline assembly to perform the most critical operataions. This initial version of the driver only supports a Cortex-M0 implementation, and can e.g. be used with the ZIP Halo LED strip for the BBC microbit: https://www.kitronik.co.uk/5625-zip-halo-for-the-bbc-microbit.html Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

led_strip: add a APA102 driver. The APA102 is a RGB LED with integrated controller. LEDs can be daisy-chained and use SPI for communication. The SPI port is configured via Device Tree. Tested on the Adafruit Trinket M0. Signed-off-by: Michael Hope <mlhx@google.com>
