generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.
dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.
The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.
Two build diagram and input-output SVG files were updated as well, along
with misc. documentation.
hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml

Before introducing the code for ARM64 (AArch64) we need to relocate the
current ARM code to a new AArch32 sub-directory. For now we can assume
that no code is shared between ARM and ARM64.
There are no functional changes. The code is moved to the new location
and the file paths are fixed to reflect this change.

Setting EEPROM_STM32 with `default y` under `if SOC_FAMILY_STM32`
overrides `depends on SOC_SERIES_STM32L1X` in EEPROM_STM32
definition.
Then, if ever EEPROM is set in any file (as in
tests/drivers/build_all`), EEPROM_STM32 will be indeed set,
with potential issues on series where driver is not yet correctly
handled.
Fix this by removing EEPROM_STM32 definition in STM32 generic
file and set `default y` along with the `depends on` to keep
it effective.

This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.
The refactoring strategy used in this commit is detailed in the issue
This commit introduces the following major changes:
1. Establish a clear boundary between private and public headers by
removing "kernel/include" and "arch/*/include" from the global
include paths. Ideally, only kernel/ and arch/*/ source files should
reference the headers in these directories. If these headers must be
used by a component, these include paths shall be manually added to
the CMakeLists.txt file of the component. This is intended to
discourage applications from including private kernel and arch
headers either knowingly and unknowingly.
- kernel/include/ (PRIVATE)
This directory contains the private headers that provide private
kernel definitions which should not be visible outside the kernel
and arch source code. All public kernel definitions must be added
to an appropriate header located under include/.
- arch/*/include/ (PRIVATE)
This directory contains the private headers that provide private
architecture-specific definitions which should not be visible
outside the arch and kernel source code. All public architecture-
specific definitions must be added to an appropriate header located
under include/arch/*/.
- include/ AND include/sys/ (PUBLIC)
This directory contains the public headers that provide public
kernel definitions which can be referenced by both kernel and
application code.
- include/arch/*/ (PUBLIC)
This directory contains the public headers that provide public
architecture-specific definitions which can be referenced by both
kernel and application code.
2. Split arch_interface.h into "kernel-to-arch interface" and "public
arch interface" divisions.
- kernel/include/kernel_arch_interface.h
* provides private "kernel-to-arch interface" definition.
* includes arch/*/include/kernel_arch_func.h to ensure that the
interface function implementations are always available.
* includes sys/arch_interface.h so that public arch interface
definitions are automatically included when including this file.
- arch/*/include/kernel_arch_func.h
* provides architecture-specific "kernel-to-arch interface"
implementation.
* only the functions that will be used in kernel and arch source
files are defined here.
- include/sys/arch_interface.h
* provides "public arch interface" definition.
* includes include/arch/arch_inlines.h to ensure that the
architecture-specific public inline interface function
implementations are always available.
- include/arch/arch_inlines.h
* includes architecture-specific arch_inlines.h in
include/arch/*/arch_inline.h.
- include/arch/*/arch_inline.h
* provides architecture-specific "public arch interface" inline
function implementation.
* supersedes include/sys/arch_inline.h.
3. Refactor kernel and the existing architecture implementations.
- Remove circular dependency of kernel and arch headers. The
following general rules should be observed:
* Never include any private headers from public headers
* Never include kernel_internal.h in kernel_arch_data.h
* Always include kernel_arch_data.h from kernel_arch_func.h
* Never include kernel.h from kernel_struct.h either directly or
indirectly. Only add the kernel structures that must be referenced
from public arch headers in this file.
- Relocate syscall_handler.h to include/ so it can be used in the
public code. This is necessary because many user-mode public codes
reference the functions defined in this header.
- Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
necessary to provide architecture-specific thread definition for
'struct k_thread' in kernel.h.
- Remove any private header dependencies from public headers using
the following methods:
* If dependency is not required, simply omit
* If dependency is required,
- Relocate a portion of the required dependencies from the
private header to an appropriate public header OR
- Relocate the required private header to make it public.

This commit adds driver support for DMA on f0/f1/f2/f3/f4/l0/l4
series stm32.
Notice due to some bugs, this is currently not working with f7.
There are two kinds of IP blocks are used across these stm32, one is the
one that has been used on F2/F4/F7 series, and the other one is the one
that has been used on F0/F1/F3/L0/L4 series.
Memory to memory transfer is only supported on the second DMA on
F2/F4 with 'st,mem2mem' to be declared in dts.
This driver depends on k_malloc to allocate memory for stream instances,
so CONFIG_HEAP_MEM_POOL_SIZE must be big enough to hold them.
Common parts of the driver are in dma_stm32.c and SoC related parts are
implemented in dma_stm32_v*.c.
This driver has been tested on multiple nucleo boards, including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/L073RZ/L476RG with the
loop_transfer and chan_blen_transfer test cases.

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.

Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.
config FOO
int
default 3
Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):
For a symbol defined in multiple locations (e.g., in a
Kconfig.defconfig file in Zephyr), it is best to only give the
symbol type for the "base" definition of the symbol, and to use
'default' (instead of 'def_<type>' value) for the remaining
definitions. That way, if the base definition of the symbol is
removed, the symbol ends up without a type, which generates a
warning that points to the other definitions. That makes the extra
definitions easier to discover and remove.
It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.
Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.

Remove the
# Omit prompt to signify a "hidden" option
comments that appear on some symbols. They seem to have been copy-pasted
at random, as there are lots of promptless symbols that don't have them
(that's confusing in itself, because it might give the idea that the
ones with comments are special in some way).
I suspect those comments wouldn't have helped me much if I didn't know
Kconfig either. There's a lot more Kconfig documentation now too, e.g.
https://docs.zephyrproject.org/latest/guides/kconfig/index.html.
Keep some comments that give more information than the symbol having no
prompt.
