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>

cmake: Fix printed list of supported boards. Fixes issue #7184. Use $BOARD_ROOT to find correct list of supported boards. This is needed since the user can set this variable to any directory. Pass $BOARD_ROOT to usage.cmake where it is called. Signed-off-by: Håkon Øye Amundsen <haakon.amundsen@nordicsemi.no>

${CMAKE_COMMAND}
cmake: ninja usage build target Fixed usage build target. Previously, `ninja usage` would print: Build flags: ninja VERBOSE=1 [targets] verbose build This is clearly wrong, as VERBOSE=1 is for make targets. To support both ninja based builds and make based build systems, the CMAKE_MAKE_PROGRAM is now exported from the calling CMake / build instance, and the verbose flag is set depending on whether ninja or make is used as build program.
