This resolves#5723 by adding support for assigning to Kconfig options
from the CMake CLI.
CMake CLI Kconfig options can be specified like so:
'cmake -DCONFIG_ASSERT=y'
The lifetime of such an option is the same as the lifetime of a CMake
cache variable, and in principle any method of populating the
CMakeCache could be used, such as cmake-gui.
This has been implemented by scanning the CMakeCache variables before
Kconfig is executed and writing any that are prefixed with 'CONFIG_'
to a new Kconfig fragment in the build directory that is merged in
with a high precedence.

Continue better integration of the runner subpackage into west by
moving the common runner configuration options into the command
core. This allows commands like "west flash -h" to display help for
common overrides like --kernel-hex.
Adjustments needed to make this happen are:
- Change the build system to separate common configuration values from
runner-specific options and arguments
- Prepare the runner core by defining a new RunnerConfig class that
represents the common configuration, and accepting that from a new
create() method, which replaces create_from_args().
- Convert all concrete runner classes to use the new style of
argument parsing and initialization.
- Group the command options appropriately for help output readability
There's still a bit of tool-specific stuff in the common
configuration (gdb and openocd configuration in particular); a more
generic way to deal with that will be necessary to better support
things like non-GDB debuggers, but that's out of scope of this patch.
All the runner-specific options are still in the runner packge, which
currently prevents them from being included in "west flash -h" etc.
Fixing that is also out of scope of this patch.
This has the ancillary benefit of getting rid of the legacy 'debug'
argument to ZephyrBinaryRunner, which is no longer appropriate since
verbose debug logging is handled by log.py in west.
Signed-off-by: Marti Bolivar <marti@opensourcefoundries.com>
Since, by design, the west 'flash', 'debug', and 'debugserver'
commands operate the same way as the Makefile targets when given no
arguments, so just delegate to west from cmake/flash/CMakeLists.txt
instead of invoking zephyr_flash_debug.py by hand.
Removing the old script is the first step towards being able to clean
up the command line argument handling in the runner package, which was
always kind of a hack and can be improved now that runner is part of a
larger tool.

This commit adds a Kconfiglib-based menuconfig implementation, built
with the standard Python 'curses' module. A new 'pymenuconfig' target is
added to run it.
The C tools are kept for now. Removing them separately allows testing of
pymenuconfig alongside the C tools, and keeps changes small and focused.
A feature is planned for later that shows all symbols -- including those
that aren't currently visible -- along with a search and "jump to"
feature. Loading of arbitrary .config files will be supported later as
well (as opposed to always loading .config/KCONFIG_CONFIG). Those
features are all connected implementation-wise.
For Windows, the wheels at
https://www.lfd.uci.edu/~gohlke/pythonlibs/#curses provide the curses
implementation. They use the standard Python curses module
(_cursesmodule.c), linked against PDCurses.
Running 'python -VV' gives the Python version and bitness, to know which
wheel to install. User documentation will be added once the C tools are
removed and the 'pymenuconfig' target is moved over to 'menuconfig'.
The CMake parts are originally by Sebastian Bøe.
Description, taken from the menuconfig.py docstring:
Overview
========
A curses-based menuconfig implementation. The interface should feel
familiar to people used to mconf ('make menuconfig').
Supports the same keys as mconf, and also supports a set of
keybindings inspired by Vi:
J/K : Down/Up
L : Enter menu/Toggle item
H : Leave menu
Ctrl-D/U: Page Down/Page Down
G/End : Jump to end of list
g/Home : Jump to beginning of list
The mconf feature where pressing a key jumps to a menu entry with
that character in it in the current menu isn't supported. A search
feature with a "jump to" function for jumping directly to a
particular symbol regardless of where it is defined will be added
later instead.
Space and Enter are "smart" and try to do what you'd expect for the
given menu entry.
Running
=======
menuconfig.py can be run either as a standalone executable or by
calling the menu.menuconfig() function with an existing Kconfig
instance. The second option is a bit inflexible in that it will
still load and save .config, etc.
When run in standalone mode, the top-level Kconfig file to load can
be passed as a command-line argument. With no argument, it defaults
to "Kconfig".
The KCONFIG_CONFIG environment variable specifies the .config file
to load (if it exists) and save. If KCONFIG_CONFIG is unset,
".config" is used.
$srctree is supported through Kconfiglib.
Other features
==============
- Seamless terminal resizing
- No dependencies on *nix, as the 'curses' module is in the Python
standard library
- Unicode text entry
- Improved information screen compared to mconf:
* Expressions are split up by their top-level &&/|| operands
to improve readability
* Undefined symbols in expressions are pointed out
* Menus and comments have information displays
* Kconfig definitions are printed
Limitations
===========
- Python 3 only
This is mostly due to Python 2 not having curses.get_wch(),
which is needed for Unicode support.
- Doesn't work out of the box on Windows
Has been tested to work with the wheels provided at
https://www.lfd.uci.edu/~gohlke/pythonlibs/#curses though.

To improve the build system's "clean build" runtime we need to cache
files in a directory outside of the build directory.
Caching files outside of the build directory is is already being done
to a certain degree today. For instance, if a user has installed
ccache it will cache files in $HOME/.ccache/.
This commit locates a directory that is suitable for caching files in
a cross-platform way. For instance on Linux this is believed to be
$HOME, on Windows this is believed to be %LOCALAPPDATA%.
If for whatever reason no environment variables are are found to be
suitable we fall back to using $ZEPHYR_BASE/.cache/. For users that
often use 'git -clean' the caching mechanism will not work as well,
but it will at least be better than no caching at all.

The actual behaviour of CONIG_FP_SOFTABI has not been matching the
documenation. The Kconfig documentation states that floating point

turning off floating point instructions instead.
This commit causes floating point instructions to be generated when
CONFIG_FP_SOFTABI is enabled, as was originally intended and
documented.
This commit can cause regressions if users have been relying on the
actual behaviour instead of the documented behaviour.
Kconfig documentation:
config FP_SOFTABI

This option selects the Floating point ABI in which hardware
floating point instructions are generated but soft-float calling
conventions.
GCC documentation:
Specifying ‘soft’ causes GCC to generate output containing library
calls for floating-point operations. ‘softfp’ allows the generation of
code using hardware floating-point instructions, but still uses the
soft-float calling conventions. ‘hard’ allows generation of
floating-point instructions and uses FPU-specific calling conventions.
