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.

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:
cmake -DBOARD=<board name> -DBOARD_ROOT=<path to boards> ..

Ninja by default will suppress command output and input. This is a
problem for the 'flash', 'debug', etc. targets, which may need to
interact with the user (and which display interactive output like
progress bars).
To fix this, add the USES_TERMINAL option to their target
definitions. This puts them in the console pool on Ninja, allowing the
commands to interact with the console.

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.

entire Kconfig "database". For Zephyr this means we no longer get a

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 intention was that the path of the file would help identify the
target, in hindsight, identifying the target has proven to not be
important.
This patch fixes#5466 by using a random string to construct the
target name instead of the path to the generated file.
