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>

scripts: gen_kobject_list: Generate enums and case statements Adding a new kernel object type or driver subsystem requires changes in various different places. This patch makes it easier to create those devices by generating as much as possible in compile time. No behavior change. Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>

scripts: Dynamically add driver subsystems to subsystems list This change extends the parse_syscalls.py script to scan for a __subsystem sentinal added to driver api declarations. It thens generates a list that is passed into gen_kobject_list.py to extend the subsystems list. This allows subsystems to be declared in the code instead of a separate python list and provides a mechanism for defining out-of-tree subsystems. Signed-off-by: Corey Wharton <coreyw7@fb.com>

build: prevent subsystems.json from being gen Actual files make terrible dependency targets in CMake. Wrap the generation of subsystems.json into a custom target to get around this. Fixes a problem where parse_syscalls.py was being called multiple times. Fixes: #23504 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

cmake: Use variables for target names There is an effort underway to make most of the Zephyr build script's reentrant. Meaning, the build scripts can be executed multiple times during the same CMake invocation. Reentrancy enables several use-cases, the motivating one is the ability to build several Zephyr executables, or images, for instance a bootloader and an application. For build scripts to be reentrant they cannot be directly referencing global variables, like target names, but must instead reference variables, which can vary from entry to entry. Therefore, in this patch, we replace global targets with variables. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
