This is one way we can support out of tree board definitions. Basically
all this needs is a board definition in the application source directory
that follows the same structure we have in the main Zephyr tree (also
allowing multiple custom boards). An application tree would look like
this for example:
boards/
CMakeLists.txt
prj.conf
README.rst
src/
with boards following the same structure as in Zephyr:
.
├── boards
│ └── x86
│ └── arduino_101
│ ├── doc
│ │ └── img
│ └── support
└── src
To use this, you need to specify the BOARD_ROOT variable on the command
line when building:

Due to a chicken-and-egg problem, it's not possible to call
board_runner_args() directly from an application CMakeLists.txt and
have it take effect:
- if the board_runner_args() call appears before including the
boilerplate file, then the function is undefined and an error
occurs.
- if the call appears after including the boilerplate file, then
board_finalize_runner_args() has already been called by the
relevant runner.board.cmake file, so it won't take effect.
Similarly to the way set_conf_file() works, allow applications to
declare additional runner args by checking if they have provided a
macro named app_set_runner_args(), which contains calls to
board_runner_args(). Using a macro means that we can invoke it with
the definition of board_runner_args() in scope.

When Kconfiglib was introduced it caused a significant performance
issue. This patch uses pruning to mitigate the performance issue.
The pruning exploits the fact that before the Kconfig database is
parsed we already know what ARCH and BOARD has been selected. So in
theory we could prune away all Kconfig sources that are not related to
the current ARCH or BOARD. In practice, it is only the Kconfig sources
in zephyr/arch/$ARCH and zephyr/board/$ARCH/ that are easy to prune.
Still, that is quite a few Kconfig sources. For qemu_x86 this patch
reduced the number of parsed Kconfig source files from 632 to
272. This pruning resulted in a incremental reconfiguration (time
cmake ..) speedup of 21% (0.56s to 0.46) and a clean build speedup of
4% (Using board qemu_x86 and sample hello_world).
Furthermore, it should be easier to maintain ARCH's and BOARD's
out-of-tree since the user now has a mechanism to redirect where
Kconfig sources are found. But this has not been explored.

Introduce Zephyr interface libraries to fix#5351.
From the documentation:
A Zephyr interface library is a thin wrapper over a CMake INTERFACE
library. The most important responsibility of this abstraction is to
ensure that when a user KConfig-enables a library then the header
files of this library will be accessible to the 'app' library.
This is done because when a user uses Kconfig to enable a library he
expects to be able to include it's header files and call it's
functions out-of-the box.
A Zephyr interface library should be used when there exists some
build information (include directories, defines, compiler flags,
etc.) that should be applied to a set of Zephyr libraries and 'app'
might be one of these libraries.
Zephyr libraries must explicitly call
zephyr_library_link_libraries(<interface_library>) to use this build
information. 'app' is treated as a special case for usability
reasons; a Kconfig option (CONFIG_APP_LINK_WITH_<interface_library>)
should exist for each interface_library and will determine if 'app'
links with the interface_library.
This API has a constructor like the zephyr_library API has, but it

I don't know why we have been passing "-serial none" to qemu but it
does not seem to be doing anything useful. So I propose we remove it.
According to the qemu documenation it should be disabling all serial
ports;
"-serial dev
Redirect the virtual serial port to host character device dev. The
default device is vc in graphical mode and stdio in non graphical
mode.
This option can be used several times to simulate up to 4 serial
ports.
Use -serial none to disable all serial ports."
But when we use "-serial none", we always combine it with "-serial
pipe", or "-serial unix", to redirect the serial port, so clearly it
is not disabling all serial ports as it attempting to do.
"-serial none" was first introduced to Zephyr in this commit:
0b54f984b8
As far I can tell, pinging an echo_server works fine without it, so I
suspect that our second -serial flag is overriding it and that it has
no effect.

The generate_inc_file_for_target() extension is a useful wrapper
around the more low-level generate_inc_file(). It takes care of
ensuring that the generated file correctly depends on it's source.
To do so it needs to name and define a custom_target, the name must be
unique, so it was constructed based on the path to the generated file,
but this caused multiple issues.

The various runners (flash/debug scripts) use environment variables to
take arguments. This is legacy behavior which is not desirable.
Use command line arguments instead.
Note: this leaves more general environment variables with publicly
documented behavior in place for now, for compatibility, e.g.:
ZEPHYR_FLASH_OVER_DFU, OPENSDA_FW, ESP_IDF_PATH, PYOCD_DAPARG
For example, when using dfu-util to flash arduino_101, instead of
setting DFUUTIL_PID, DFUUTIL_ALT, and DFUUTIL_IMG environment
variables, have the script invocation look like this:
python3 .../zephyr_flash_debug.py dfu-util flash \
[common arguments omitted] \
--pid=8087:0aba --alt=x86_app \
--img=.../build/zephyr/zephyr.bin
Make similar changes for other runners (openocd, etc.) and
targets (debug, debugserver).
To implement this in the scripts:
- have the individual scripts/support/runner/some-runner.py files
register their own command line arguments
- teach them to construct instances from arguments, not the
environment
- have zephyr_flash_debug.py request runners to register command
line argument parsers, and handle arguments
In the build system:
- add a new board_runner_args() extension function that board.cmake
files can use to add to the zephyr_flash_debug.py command line
- adjust cmake/flash/CMakeLists.txt to invoke with arguments
- add new helper include files for each runner (like
boards/common/dfu-util.board.cmake, etc.), which add default
options as needed and then add on overrides from
board_runner_args() calls
- update board.cmake files to use the new includes and extension
This implied some tweaking when using openocd to make the CMake string
escaping and unescaping work properly.

The Python-based runners have replaced the old shell scripts. Refactor
the build system accordingly:
- FLASH_SCRIPT is now BOARD_FLASH_RUNNER
- DEBUG_SCRIPT is now BOARD_DEBUG_RUNNER
The values, rather than being the names of files, are now the names of
runners in scripts/support/runner. They are still short, descriptive
names like "openocd", "jlink", "em-starterkit", etc.
Adjust the zephyr_flash_debug.py call and runner internals
accordingly. Have each runner class report a name and the commands it
can handle. This lets us move some boilerplate from each do_run()
method into the common run() routine, and enables further improvements
in future patches.
The handles_command() method is temporary, and will be replaced by a

device tree awareness to the runners.

The desired behaviour is that when a flag that is given through the
zephyr_* API conflicts with the zephyr_library_* API then precedence
will be given to the zephyr_library_* API. In other words, local
configuration overrides global configuration.
We choose to rely upon the compiler for sane behaviour when flags are
in conflict. Compilers generally give precedence to flags given late
on the command line. So to ensure that zephyr_library_* flags are
placed late on the command line we create a dummy interface library
and link with it to obtain the flags.
Other options were considered, source file properties would also have
higher priority. But that would have required some kind of
post-processing stage that applies all the source file properties.
Linking with a dummy interface library will place flags later on the
command line than the the flags from zephyr_interface because
zephyr_interface will be the first interface library that flags are
taken from.

or ISSM provided by Intel, will contain only the compiler, linker, and
supporting tools. Other binaries needed by the build system that are
provided by the Zephyr SDK need to be found somewhere else.

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
