This adds a choice of three different libc API buffer overflow detection
modes:
* None
* Compile-time
* Compile-time and Run-time
These correspond with the clang/gcc _FORTIFY_SOURCE modes (0/1/2).
_FORTIFY_SOURCE depends on compiler optimizations and require libc support
which the minimal C library doesn't include, so _FORTIFY_SOURCE is disabled
by default in those cases. Native tooling might also enable
_FORTIFY_SOURCE, so don't enable it by default in that case either.

Linker scripts contains a `.last_section` section that is placed in rom
region as NOLOAD for the purpose of retrieve the actual number of bytes
contained in the image. See d85efe0b10
However, a previous section may cause the location counter to be
incremented for alignment purposes. This can result in the size of the
image to be 0x10FA but location counter to be 0x1100 because it has been
aligned for next section placement.
Therefore, two new Kconfig settings are introduced.
Those settings request the linker to will write a pattern in
`.last_section`. Together with removing NOLOAD and writing a patten to
the section then we ensure that data is written after alignment of
location counter, and thereby forces the image size to be in sync with
the location counter.
The default pattern used will be 0xE015 (end of last section).
Some systems may fill up the flash completely, or simply write data at
the end of the flash, which in both cases can result in overflow.
Therefore, the new settings can be disabled.

There are few cases where removing this enforcement is desirable:

This commit is motivated by the west discussion in:
https://github.com/zephyrproject-rtos/west/issues/548
The commit provides the ability to generate a build meta info file
containing lists of:
- Zephyr: path and revision
- Zephyr modules: name, path, and revision
- West: manifest path
path and revision for each project
For Zephyr or Zephyr modules the revision will be `null` if it is not
under git version control.
If Zephyr, a modules, or a project has uncommitted changes, the revision
will be marked dirty.
If west is not installed or used for the build process, the
west-projects list will be empty.
If a project is both a Zephyr module and a west project it will show up
in both lists.
Similar to Zephyr, which is independently referred as the Zephyr in use
but also listed as west project when west is used.
This is important in case ZEPHYR_BASE was manually set and pointing to
a different Zephyr repository.
The build meta file is not created per default but can be enabled with
the BUILD_OUTPUT_META Kconfig setting.

This commit introduces MODULE_EXT_ROOT which allows CMake and Kconfig
glue code to be placed outside of the Zephyr module repository.
This allows for placing glue code in Zephyr, but also allows users to
specify custom MODULE_EXT_ROOTs for glue code using either
`-DMODULE_EXT_ROOT` or `zephyr/module.yml` with
`build:settings:module_ext_root` settings.
MODULE_EXT_ROOT' is a list of directories, similar to other roots such
as BOARD_ROOT, DTS_ROOT, etc.
The Zephyr repo folder ${ZEPHYR_BASE} is always to the MODULE_EXT_ROOT
list as lowest priority.
For each MODULE_EXT_ROOT, the file
`<module_ext_root>/modules/modules.cmake` will be processed.
In Zephyr repo, the folder `modules/<module>/` contains CMakeLists.txt
and Kconfig glue code for the Zephyr module.
A Zephyr module can specify that CMakeLists.txt and Kconfig glue code is
placed in an external module root by specifying:
```
build:
cmake-ext: True
kconfig-ext: True
```
It is still possible to place the CMakeLists.txt and Kconfig files
directly in the Zephyr module using the existing:

This default-y option allows continued use of the legacy devicetree

There are no functional changes yet, but when this is default n,
old-style DT code won't build. At that point, adding any of these will
be a fix to keep old-style code working:
- "CONFIG_LEGACY_DEVICETREE_MACROS=y" to prj.conf
- "-- -DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the west build command
- "-DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the cmake command
This option can be changed to default n in time for the Zephyr 2.3
release. That will provide users of Zephyr 2.2 with a smooth migration
path to the new devicetree.h API after 2.3 is released, which
nonetheless will alert them immediately that something is wrong due to
build errors.
Unfortunately, __DEPRECATED_MACRO is not sufficient in all cases as a

Group the 'source's of Kconfig.defconfig files together to make it
clearer what the comment is talking about. Remove blank lines between
the other 'source's too, splitting the 'source's into two groups.
Also touch up the comment to make it more concrete and shorten it a bit.
Mention that it applies to 'choice's as well.

Even though it looks logical to not expose BUILD_NO_GAP_FILL
when we don't expect to use objcopy for creation of .bin, .hex etc
in reality generation of at least zephyr.hex happens if one wants
to use openocd runner, see CMakeLists.txt:
---------------------------->8----------------------
if(CONFIG_BUILD_OUTPUT_HEX OR BOARD_FLASH_RUNNER STREQUAL openocd)
set(out_hex_cmd "")
set(out_hex_byprod "")
set(out_hex_sections_remove
.comment
COMMON
.eh_frame
)
bintools_objcopy(
RESULT_CMD_LIST out_hex_cmd
RESULT_BYPROD_LIST out_hex_byprod
STRIP_ALL
GAP_FILL ${GAP_FILL}
TARGET_OUTPUT "ihex"
SECTION_REMOVE ${out_hex_sections_remove}
FILE_INPUT ${KERNEL_ELF_NAME}
FILE_OUTPUT ${KERNEL_HEX_NAME}
)
list(APPEND
post_build_commands
${out_hex_cmd}
)
list(APPEND
post_build_byproducts
${KERNEL_HEX_NAME}
${out_hex_byprod}
)
endif()
---------------------------->8----------------------
So if there's a good reason to disable gap filling
(like funny memory map wit huuuuge holes) let's keep that opportunity
instead of relying on sanity of all the other code.

Allow a given toolchain to specify Kconfig options that might be
relevant to a feature available in that toolchain.
For example, the ARM embedded GNU toolchain supports two variants of
newlib and you select the smaller one via a spec file. We can use a
Kconfig option like HAS_NEWLIB_LIBC_NANO to convey that this feature is
supported by that toolchain.
We look for the toolchain Kconfig in ${TOOLCHAIN_KCONFIG_DIR}/Kconfig,
and default TOOLCHAIN_KCONFIG_DIR to:
${TOOLCHAIN_ROOT}/cmake/toolchain/${ZEPHYR_TOOLCHAIN_VARIANT})
toolchain specific cmake files can override the default if needed.
Additionally tweaked the zephyr/generic.cmake to use
${CMAKE_CURRENT_LIST_DIR} to reduce some duplication.

Add an opt-in feature that will generate a Makefile with build
variables like CC, and KBUILD_CFLAGS for consumption by third-party
Make-based build systems.
This emulates the 'outputexports' target that KBuild supported and is
supported for the same reasons that KBuild supported it. Easier

Out-of-tree code can still be using the old file locations. Introduce

USE_CODE_PARTITION is a bit vague as a symbol name ("use code partition
how?"). Rename it to USE_DT_CODE_PARTITION to make it clearer that it's
about devicetree.
This would break any third-party configuration files that set it, but
it'll generate an error since kconfig.py promotes warnings to errors, so
it's probably not a big deal.

The prompt and help string for USE_CODE_PARTITION were too terse and
didn't make it clear that it's related to devicetree, which confused me.
Spell things out in more detail.
Unless the meaning of a symbol is completely obvious from context, aim
for at least a few sentences of help text. Think about what would be
confusing for someone coming at it without much context.

Having FLASH_LOAD_OFFSET and FLASH_LOAD_SIZE always configurable froze
their values at 0 when BOOTLOADER_MCUBOOT was enabled in menuconfig,
when instead the values from /chosen/zephyr,code-partition in devicetree
should be used. BOOTLOADER_MCUBOOT selects USE_CODE_PARTITION, which is
a flag to use the devicetree information.
To fix it, only make FLASH_LOAD_OFFSET and FLASH_LOAD_SIZE configurable
when USE_CODE_PARTITION is disabled. It looks like no configuration
files set them at the moment.
See the added documentation in
https://github.com/zephyrproject-rtos/zephyr/pull/20722 for an
explanation of why this happens. This bit novalisek in
https://github.com/zephyrproject-rtos/zephyr/issues/20673.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

FLASH_LOAD_SIZE gets its default from the $(dt_chosen_reg_size)
function, which is defined in scripts/kconfig/kconfigfunctions.py.
$(dt_chosen_reg_size) returns a decimal value rather than a hex value.
Previously, FLASH_LOAD_SIZE was declared as hex, which made Kconfiglib
automatically prepend 0x to its value (the same logic is in the C
Kconfig tools). This gave an incorrect size in .config, e.g.
CONFIG_FLASH_LOAD_SIZE=0x374784 where CONFIG_FLASH_LOAD_SIZE=374784 was
intended.
Fix it by changing the type of FLASH_LOAD_SIZE to int. All other symbols
that use $(dt_node_reg_size) and $(dt_chosen_reg_size) are int too
(FLASH_SIZE and SRAM_SIZE, plus BOOTLOADER_SRAM_SIZE is also int).
This has some subtle breakage potential in that FLASH_LOAD_SIZE has a
prompt (is user-configurable in the menuconfig or by changing .config
files). Nothing seems to directly assign in Zephyr at least.

Convert how we get the various chosen properties like "zephyr,console"
to use the new kconfig functions like dt_chosen_to_label.
Because of how kconfig parses things we define a set of variables of the
form DT_CHOSEN_Z_<PROP> since comma's are parsed as field seperators in
macros.
This conversion allows us to remove code in gen_defines.py for the
following chosen properties:
zephyr,console
zephyr,shell-uart
zephyr,bt-uart
zephyr,uart-pipe
zephyr,bt-mon-uart
zephyr,uart-mcumgr

This script is looking for a hyperspecific error (mismatched padding
when linking into two simultaneous output sections) that bit us once,
in an era where the linker scripts were less unified. We haven't seen
it crop up since, and multiple platforms have changed the way they do
this anyway.
It's needless complexity. Junk it.
