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: provide a useful error msg when native compiler is missing This avoids a cryptic DTC failure when compiling trying to compile native_posix with a missing gcc or clang. REQUIRED is available since CMake 3.18 Example with clang, cryptic error without this commit: ``` ZEPHYR_TOOLCHAIN_VARIANT=llvm west build \ -p -b native_posix samples/hello_world/ -- Found toolchain: host (clang/ld) <= this is wrong -- Found Dtc: /usr/bin/dtc (found suitable version "1.6.1", minimum ... -- Found BOARD.dts: zephyr/boards/posix/native_posix/native_posix.dts CMake Error at /zephyr/cmake/modules/dts.cmake:191 (message): command failed with return code: No such file or directory Call Stack (most recent call first): zephyr/cmake/modules/zephyr_default.cmake:113 (include) zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:66 (include) zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:92 (include_boil... CMakeLists.txt:5 (find_package) ``` Well hidden behind the scenes, dts.cmake fails above because it invokes `CMAKE_C_COMPILER-NOTFOUND` With this commit: ``` ZEPHYR_TOOLCHAIN_VARIANT=llvm west build \ -p -b native_posix samples/hello_world/ -- Found toolchain: host (clang/ld) <= this is still wrong CMake Error at zephyr/cmake/compiler/clang/generic.cmake:7 (find_program): Could not find CMAKE_C_COMPILER using the following names: clang ``` Signed-off-by: Marc Herbert <marc.herbert@intel.com>
