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.

cmake: enable -Wshadow partially for in-tree code This enables -Wshadow to warn about shadow variables on in tree code under arch/, boards/, drivers/, kernel/, lib/, soc/, and subsys/. Note that this does not enable it globally because out-of-tree modules will probably take some time to fix (or not at all depending on the project), and it would be great to avoid introduction of any new shadow variables in the meantime. Also note that this tries to be done in a minimally invasive way so it is easy to revert when we enable -Wshadow globally. Source files under modules/, samples/ and tests/ are currently excluded because there does not seem to be a trivial way to add -Wshadow there without going through all CMakeLists.txt to add the option (as there are 1000+ files to change).

arch: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for arch files. Normally a syscall would check the current privilege level and then decide to go to _impl_<syscall> directly or go through a _handler_<syscall>. __ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will make all the system calls from the arch files directly link to the _impl_<syscall>. Thereby reducing the overhead of checking the privileges. In the previous implementation all the source files would be compiled by zephyr_source() rule. This means that zephyr_* is a catchall CMake library for source files that can be built purely with the include paths, defines, and other compiler flags that all zephyr source files uses. This states that adding one extra compiler flag for only one complete directory would fail. This limitation can be overcome by using zephyr_libray* APIs. This creates a library for the required directories and it also supports directory level properties. Hence we use zephyr_library* to create a new library with macro _ZEPHYR_SUPERVISOR_ for the optimization.

arch: Simplify private header include path configuration. When compiling the components under the arch directory, the compiler include paths for arch and kernel private headers need to be specified. This was previously done by adding 'zephyr_library_include_directories' to CMakeLists.txt file for every component under the arch directory, and this resulted in a significant amount of duplicate code. This commit uses the CMake 'include_directories' command in the root CMakeLists.txt to simplify specification of the private header include paths for all the arch components.

cmake: fix include directories to work with out-of-tree arch Include directories for ${ARCH} is not specified correctly. Several places in Zephyr, the include directories are specified as: ${ZEPHYR_BASE}/arch/${ARCH}/include the correct line is: ${ARCH_DIR}/${ARCH}/include to correctly support out of tree archs.

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> 2017-10-27 15:43:34 +02:00			`add_subdirectory(common)`
Build: Added support for out-of-tree Arch Introduces the ARCH_ROOT argument, similar to BOARD_ROOT and SOC_ROOT. This enables support for out-of-tree architectures. The ARCH_ROOT out-of-tree layout is expected to be the following: * ${ARCH_ROOT}/arch/${ARCH}/ * ${ARCH_ROOT}/include/arch/${ARCH}/ (Optional) Signed-off-by: Klaus Petersen <kape@oticon.com> 2018-11-15 10:37:46 +01:00			`add_subdirectory(${ARCH_DIR}/${ARCH} arch/${ARCH})`
