ab7ec17b86 cmake: zephyr module processing improvements.
This commit improves Zephyr modules support in CMake.
All Zephyr modules will now have a corresponding
`ZEPHYR_${module_name}_MODULE_DIR` set, regardless of whether they
define a cmake folder in module.yml.

This results in:
`ZEPHYR_${module_name}_MODULE_DIR` defined for all modules and refers to
the root of the modle.
`ZEPHYR_${module_name}_CMAKE_DIR` defined for modules that specifies
cmake in module.yml, or is having both a CMakeLists.txt and Kconfig file
in the zephyr folder.

5b1b4a3755 sanitycheck: need to wait for harness to process QEMU outputs
There is a potential that QEMUHandler.handle() returns before

Simply wait for the harness thread to finish before returning.

Also, fix the return code in the debug message as it should be

49206a86ff debug/coredump: add a primitive coredump mechanism
This adds a very primitive coredump mechanism under subsys/debug
where during fatal error, register and memory content can be
dumped to coredump backend. One such backend utilizing log
module for output is included. Once the coredump log is converted
to a binary file, it can be used with the ELF output file as
inputs to an overly simplified implementation of a GDB server.
This GDB server can be attached via the target remote command of
GDB and will be serving register and memory content. This allows
using GDB to examine stack and memory where the fatal error
occurred.

203556cd8c sanitycheck: update section names in size calculator
Commit 8d7bb8ffd8 refactored
device structures which changed some of the linker sections:
"devconfig" was removed, and "devices" was added. However,
the list in sanitycheck's size calculator was not updated,
which results in sanitycheck complaining about unrecognized
sections when doing footprint.

Also, a few sections have been renamed (with added suffix
"_area") due to introduction of Z_ITERABLE_SECTION_RAM/ROM
macros. There are also some missing section names.

Fixes the issue by adding the missing sections names, and
updating existing ones.

716ab47dcc west: try image-1's size as slot size in imgtool
When MCUBoot is built using the swap-move strategy, the secondary slot
can be one sector smaller than the primary slot, because the primary
slot's last "useful" image sector must be "reserved" for the move
operation; this impacts the generation of padded images, so when
signing an image, the proper size to use is the secondary slot's,
unless a secondary image is not defined which is the case when using
single image DFU.

e49e3c8fef scripts: update checkpatch based on current linux kernel version
This squashes and applies the Linux diffs to scripts/checkpatch.pl
between Linux commit 16fbf79b0f83bc75 ("Linux 5.6-rc7") and
9123e3a74ec7b93 ("Linux 5.9-rc1") except for commits identified below.

The last 1000 commits to Zephyr master were compared for checkpatch
output differences between the previous Zephyr version and this
version.  One new diagnostic about function declarations with an empty
parameter-list was introduced (FUNCTION_WITHOUT_ARGS).  The text of an
existing diagnostic was changed (DT_SPLIT_BINDING_PATCH).  The text of
LONG_LINE diagnostics was enhanced to provide the actual line length.

Linux commit dfa05c28ca7ffc0a ("checkpatch: remove email address
comment from email address comparisons") was removed because
differences in the scripts resulted in false signed-off-by check
diagnostics when a full name included characters not in Basic Latin,
due to changes in how the author name was extracted.  Earlier upstream
changes not integrated into Zephyr may be required.

Linux commit b95692f8b3000166 ("checkpatch: prefer fallthrough; over
fallthrough comments") was removed because Zephyr doesn't support the
upstream pseudo keyword.

Linux commit bdc48fa11e46f867 ("checkpatch/coding-style: deprecate
80-column warning") was edited to not actually change the 80-column
maximum line limit as this change has not been mooted for Zephyr.

Linux commit ced69da1db0b57bb ("checkpatch: fix CONST_STRUCT when
const_structs.checkpatch is missing") was edited to the CONST_STRUCT
file as that's not supported in Zephyr.

edde894d04 cmake: Zephyr CMake package clean-up and minor fix
Fixes: #27375

This is a cleanup of the Zephyr CMake package export.
The code has been simplified so that the export now happens through a
CMake script. This avoids several generated CMake build files compared
to previous export mode, and thus removes the need for a CMake pristine
script.

A benefit of this cleanup is that it also fixes #27375.

9ca1de18eb scripts: west_commands: add .config parsing helper
Rolling yet another parser turns out to be the best way to let west
extensions respond to Kconfig values. See source code comments in the
patch for details.

The sanitylib library has some similar functionality but it isn't
exactly the same, and it gets strings wrong. For example, that parser
can't handle this option:

CONFIG_FOO="he said \"no\" to me"

This one can, and it has a couple of other features we'll find useful
for west extensions eventually besides.

(Not to mention that sanitylib also rolled its own CMake cache parser,
which also exists in west_commands.)

25d57ba5af modules: adding support for ROOTs definitions in zephyr/module.yml
Fixes: #25215

This commit introduces the possibility of defining ROOTs in a Zephyr

Supported with this commit:
- BOARD_ROOT
- SOC_ROOT
- DTS_ROOT
- ARCH_ROOT

In order to support this in Zephyr module files, the detection of west
has been moved to dedicated west.cmake file and included immediately
after python.cmake.

Also the inclusion of zephyr_modules.cmake has moved before first use
of BOARD_ROOT.

5f7cc8ded9 cmake: kconfig: support for multiple SOC_ROOT
This commit introduces support for multiple SOC_ROOT.

This means that additional SOC_ROOTs specified using -DSOC_ROOT as
argument to CMake will be forming a list together with ${ZEPHYR_BASE}.

This allows for greater flexibility, as developers can now specify
multiple out-of-tree SoCs and not worry about the SoC used for the
board they compile for.

Also it avoid code, such as:
if(BOARD STREQUAL my_board_using_out_of_tree_soc)
  set(SOC_ROOT some/out/of/tree/soc/path)
endif()
in application CMakeLists.txt.

Finally, allowing multiple SOC_ROOTs prepares for specifying SOC_ROOTs
in Zephyr modules.

- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF

If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.

Separately generated privilege elevation stacks are now declared
like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN.

555fc6dbd5 sanitycheck: fix only_tags usage
We have been doing an AND comparison instead of an OR. AND does exclude
way to many testcases where multiple tags are being used.

1636c316d9 sanitycheck: introduce integration testing
Use --integration testing for CI to limit execution and builds on
platforms that actually provide most of the coverage instead of blindly
building/running on all available platforms.

2dad0b4500 scripts/requirements: add lpc_checksum script
On some NXP LPC MCUs (such as LPC11U6x), a valid firmware image must
include a checksum in the 7th entry of the ARM Cortex-M0 exception
vector table. This checksum is verified by the bootloader.

The lpc_checksum.py python script allows to insert this checksum into
the firmware images (BIN and HEX formats).
