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>

REGEX "^#define CONFIG_"
cmake: Support UTF-8 characters in Kconfig values We are using the CMake command 'file(STRINGS' (which defaults to only decoding ASCII) to read Kconfig configurations. When UTF-8 characters are detected they are treated as newlines. This behaviour has caused issues when users have input UTF-8 characters into Kconfig values. E.g. USB device descriptor strings. This commit adds the flag 'ENCODING "UTF-8"' to the 'file(STRINGS' command so that UTF-8 characters are correctly passed through the build system.

cmake: kconfig: fix issue if Kconfig symbol name contains lower case Fixes: #40420 If a Kconfig has lower case in its symbol name, then the file configs.c is wrongly generated. For example a Kconfig snippet like this: > config FAIL_this > bool "Test fail" > default y will create an autoconf.h containing this: > #define CONFIG_FAIL_this 1 but the configs.c will wrongly contain the same > #define CONFIG_FAIL_this 1 instead of: > GEN_ABSOLUTE_SYM_KCONFIG(CONFIG_FAIL_this, 1); which results in following error at compile time .../build/zephyr/misc/generated/configs.c: In function '_ConfigAbsSyms': .../build/zephyr/misc/generated/configs.c:309: warning: "CONFIG_FAIL_this" redefined 309 | #define CONFIG_FAIL_this 1; | In file included from <command-line>: .../build/zephyr/include/generated/autoconf.h:299: note: this is the location of the previous definition 299 | #define CONFIG_FAIL_this 1 | The file misc/generated/CMakeLists.txt has been updated to correctly handled lower casing in Kconfig symbol names.
