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>

cmake: Fall back to ZEPHYR_BASE when the board is not in BOARD_ROOT It is very inconvenient to maintain an application that both runs on a Zephyr board and an out-of-tree board. It forces one to write build scripts like this in the app: if(BOARD STREQUAL my_out_of_tree_board) set(BOARD_ROOT some/out/of/tree/board/path) endif() To avoid this we change the semantics of BOARD_ROOT. Instead of it being a path to the board root it is now a prioritized list of board root directories. Zephyr will append ZEPHYR_BASE to BOARD_ROOT. This ensures that Zephyr boards can be used when the out-of-tree board directory can not supply the requested board. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>

cmake: dts: move to specifying shield on the command line Rather than specifying SHIELD via Kconfig, we move it to being specified via the command line, similar to board. So we can do: -DSHIELD=x_nucleo_iks01a1 or, for multiple shields: -DSHIELD="x_nucleo_iks01a1 frdm_kw41z" Following cmake change, update x_nucleo_iks01a1 sample in order not to enable CONFIG option anymore but set SHIELD cmake option. Last, update documentation to reflect this change. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org> Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

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.
