Usually Zephyr boots all secondary CPUs as a part of system
boot. Some applications however need an ability to boot on
the main CPU only and enable secondary CPUs selectively at
run-time. Add a Kconfig option to support this behaviour.
When booting CPUs on demand applications also need helpers
to initialise a dummy thread and begin threaded execution
on those CPUs, add two such helpers.

Set options that are definitely true or false to True or False in the
options dict. Add a 'getboolean' method that also allows a fallback to
False in case the option is not mentioned in .config due to unmet
dependencies. This allows calling code to just ask about the option
they are interested in, even if the .config file doesn't mention the
option at all.
Propagate this to users within the runners package and 'west sign',
taking advantage of the new build_conf property.
Rename the 'bcfg' internal variable in sign.py to 'build_conf' to
match other source files that use BuildConfiguration instances, to
make it easier to grep for users.

Instead of mocking out the BuildConfiguration class, just create its
input file and let the real class do the work.
This in turn exposes a bug in the way the board name is being pulled
out of the BuildConfiguration, which we fix to keep the tests passing.

Defer loading .config until we really need it, when we are flashing a
binary. Pre-emptively loading it is wasted effort if we're flashing a
.hex, which has been the default behavior when possible since
dcaabb860f ("west: runners: jlink: prefer .hex over .bin").

JLink versions like 'V7.0a' do not conform to PEP 440 version
conventions; the 'a' part is used by PEP 440 compliant versions for
alphas. It gets parsed to a legacy type by the packaging library,
which always is treated as a lower value when compared with a
conforming version string.
To fix, get the version from the shared library distributed with the
JLink tools. This has the side benefit of making the code work on
Windows. That's merely a nice to have for -nogui 1 detection for now,
but will be essential in the next commit.

This option has existed since the beginning of the runners package,
which greatly predates the way DT is used in zephyr right now. It

Copy a fix from test_nrfjprog.py to the other runner test suites. The
current code will enter an infinite recursion if you hit the path
where os.path.isfile is called, since it's been patched to
os_path_isfile_patch in the calling context. The fix is to cache the
'real' version in the parent scope and call it directly as a fallback.

Fix buffer leak in L2CAP and SMP when attempting to send over a
a connection that has been disconnected.
Both L2CAP and SMP now have ownership of the buffer in case of failure
to send it and need to unref it in case of send failure.
Change the return type of bt_l2cap_send since the user of this function
has to handle releasing of the buffer when this fails.

For non-specified archs, including those out-of-tree, the possibility to

This adds FPU sharing support with a lazy context switching algorithm.
Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr
currently doesn't support such a build.
It is therefore possible to do FP access in IRS as well with this patch
although IRQs are then disabled to prevent nested IRQs in such cases.
Because the thread object grows in size, some tests have to be adjusted.

Add the exception depth count to tpidrro_el0 and make it available

CONFIG_FPU: The architecture dependency list is redundant.
Having CPU_HAS_FPU being selected by those archs as a dependency
is sufficient and cleaner.
CONFIG_FPU_SHARING: The default should always be y to be on the safe
side here, but as a compromise for not affecting existing config, let's
move the default selection local to those configs that care, again to
avoid a growing list of conditionals here. Adjust the help text which
