This commit introduces Zephyr SDK CMake config package.
This removes the need for setting ZEPHYR_SDK_INSTALL_DIR and
ZEPHYR_TOOLCHAIN_VARIANT when using Zephyr SDK in Linux.
It also allows to introduces never SDKs without breaking Zephyr.
For example, with this PR, the current Zephyr SDK is 0.11.1 but when
releasing 0.12 then the current Zephyr will no longer built.
This PR moves the Zephyr SDK CMake related code to the SDK and thus
allowing to use newer SDKs, as long as they are backwards compatible.
It also allows multiple SDK installations, and will automatically select
the version closet to the required version.

Added support for Qemu User Networking and tested with
qemu_x86 model. The support is kept simple assuming that
the TAP interface will always be preferred for more
sophisticated / practical use cases.
QEMU User Networking is implemented using "slirp", which
provides a full TCP/IP stack within QEMU and uses that
stack to implement a virtual NAT'd network. As this
support is built into QEMU, it can be used with any model
and requires no admin privileges on the host machine,
unlike TAP.
Added documentation to facilitate the user.

The QEMU '-semihosting' option enables the emulation of the semihosting

In order to support semihosting console output, the QEMU semihosting
feature is enabled and its console is connected to the console backend
chardev.

\. and . to parse literal dots; the second one matches any character.
Just use [.] instead in both cases.
2. Don't error out if the installed dtc is too old. It's optional, so

This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).
Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

The ARM GCC `-march` compiler flag is completely redundant when the
`-mcpu` flag is specified, since the `-mcpu` selects the target ARM
architecture as well as CPU-specific optimisations.
In fact, it is disadvantageous to specify both `-march` and `-mcpu`
flags because the `-march` flag overrides and disables any CPU-specific
optimisations enabled by the `-mcpu` flag.

This commit adds the GCC `-mabi=lp64` flag to force the LP64 (64-bit
long and pointer) ABI, which is mandatory for running the Zephyr
AArch64 architecture port.
Note that this flag is, strictly speaking, not necessary in most cases
because the AArch64 GCC defaults to using the LP64 ABI. This flag is
required, however, if compiling Zephyr with a GCC that is configured
with `--with-abi=ilp32`, which makes ILP32 the default ABI.

Using find_package(Python3 3.6) will select the highest available
python3.
This means that in case user has:
/usr/bin/python --> python2.7
/usr/bin/python3 --> python3.6
/usr/bin/python3.6
/usr/bin/python3.8
then CMake will choose python 3.8.
This commit changes that behavior, so that in the above scenario, then
Python 3.6 will be preferred.
It also adds the following, python will be preferred over python3, if
both meets the minimum requirement.
For example:
/usr/bin/python --> python3.6
/usr/bin/python3 --> python3.7
then Python 3.6 is prefered.
It further introduces PYTHON_PREFER variable, which can be used to
further control the behavior.
As example -DPYTHON_PREFER=python3.7 will choose Python 3.7 if
installed.

This commit switches to use the find_package(Python3) introduced with
CMake 3.12.
This removes the need for a Zephyr backport of Python detection module.
The search order for Python3 is following CMake search order and can be
controlled through CMake flags (See CMake documentation).
Default it will use the Python version found in PATH.
If multiple Python3 versions are found in PATH, the newest version will
be selected (Can be controlled using `Python3_FIND_STRATEGY`)
Using find_package(Python3) also ensures Python2.7 will never be
selected, issue #11103, which was re-introduced in Zephyr.

This commit includes the following fixes in order to remove environment
setting of ZEPHYR_BASE is west extension commands.
- Build command
west build --pristine will now use the ZEPHYR_BASE variable found
in CMakeCache.txt in the build folder.
This ensures that the pristine command is executed from the same
Zephyr that was used for compilation.
- Board command
The west boards command no longer sets Zephyr base before invoking
cmake -P cmake/boards.cmake
Instead boards.cmake uses find_package(Zephyr) to ensure consistent
behavior with Zephyr samples, so that the detection of Zephyr base is
uniform across CMake commands.
It also changes BOARD_ROOT_SPACE_SEPARATED to BOARD_ROOT in order to
be consistent with existing user documentation.

When ZephyrConfig package is being version checked, then

This is joint work with Kumar Gala (see signed-off-by).
This supports a new devicetree macro syntax coming. It's not really
worth mixing up the old and the new generation scripts into one file,
because:
- we aim to remove support for the old macros at some point, so it
will be cleaner to start fresh with a new script based on the old one
that only generates the new syntax
- it will avoid regressions to leave the existing code alone while
we're moving users to the new names
Keep the existing script by moving it to gen_legacy_defines.py and
changing a few comments and strings around. It's responsible for
generating:
- devicetree.conf: only needed by deprecated kconfigfunctions
- devicetree_legacy_unfixed.h: "old" devicetree_unfixed.h macros
Put a new gen_defines.py in its place. It generates:
- zephyr.dts
- devicetree_unfixed.h in the new syntax
Include devicetree_legacy_unfixed.h from devicetree.h so no DT users
are affected by this change.

The header printed at the beginning of every west build is kind of

There are two problems with the way runners.yaml is being created:
1. The dictionary which contains the arguments for each runner is
using the runner's name converted to a C identifier instead of the
runner's name itself. That causes west flash to fail when the two
are different, e.g. for 'misc-flasher' (runner name), which is
different than 'misc_flasher' (runner name as C identifier)
2. We need to make sure that the dictionary key maps to an empty list
if there are no arguments, which normally doesn't happen since the
runner usually at least takes the path of the file to flash or debug.
It does happen in the case of misc-flasher, though, since the whole
point of that runner is that it's an escape hatch for people with
out of tree scripts that nevertheless want 'west flash' integration
for things like sanitycheck device testing.
3. A copy/paste error is setting the debug runner to the flash runner.
Fix them all.
