Torsten Rasmussen bb3946666f 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.

Stephanos Ioannidis 7bcfdadf81 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.

Anas Nashif 3ae52624ff 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.

Klaus Petersen c66cb76fed 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)

Adithya Baglody 5ab3960c75 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.

Sebastian Bøe 12f8f76165 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
