The xtensa/sample_controller linker script is missing the necessary

3d82c7c828 linker: align _image_text_start/end/size linker symbols name
Cleanup and preparation commit for linker script generator.

Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.

The symbols _image_text_start and _image_text_end sometimes includes
linker/kobject-text.ld. This mean there must be both the regular
__text_start and __text_end symbols for the pure text section, as well
as <group>_start and <group>_end symbols.

The symbols describing the text region which covers more than just the
text section itself will thus be changed to:
_image_text_start -> __text_region_start
_image_text_end   -> __text_region_end

c6aded2dcb linker: align _image_rodata and _image_rom start/end/size linker symbols
Cleanup and preparation commit for linker script generator.

Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.

The symbols _image_rom_start and _image_rom_end corresponds to the group
ROMABLE_REGION defined in the ld linker scripts.

The symbols _image_rodata_start and _image_rodata_end is not placed as
independent group but covers common-rom.ld, thread-local-storage.ld,
kobject-rom.ld and snippets-rodata.ld.

This commit align those names and prepares for generation of groups in
linker scripts.

The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end   -> __rom_region_end

The rodata will also use the group symbol notation as:
_image_rodata_start -> __rodata_region_start
_image_rodata_end   -> __rodata_region_end

7d37fe21d1 cmake: c++ exceptions linking support
Fixes part of: #32448

This commit updates the CMake CMAKE_CXX_LINK_EXECUTABLE to include
crtbegin.o and crtend.o at the right locations when linking with gcc.

It also updates linker scripts to ensure proper location of the
exception header frame sections.

This ensure proper handling of exceptions for those architectures
- x86
- xtensa
- riscv32

4e85006ba4 dts: Rename generated_dts_board*.{h,conf} to devicetree*.{h,conf}
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
update.

00c7ce7942 linker: move where we define _LINKER and _ASMLANGUAGE
Move _LINKER and _ASMLANGUAGE to target.cmake because of how we pick the
linker script that might be used.  This way regardless of how or where a
linker.ld gets included we will always set _LINKER & _ASMLANGUAGE (so
any header that needs check based on those defines they can,
specifically generated_dts_board.h)

70fb574a6e linker: cxx: xtensa: Added .gcc_except_table.*
Make sure that all sub-sections of .gcc_except_table are mapped in
rodata else C++ builds with exceptions enabled will generate warnings
due to orphan sections.

506f15c381 interrupts: simplify position of sw ISR table
We now place the linker directives for the SW ISR table
in the common linker scripts, instead of repeating it
everywhere.

The table will be placed in RAM if dynamic interrupts are
enabled.

A dedicated section is used, as this data must not move
in between build phases.

6600c64331 linker: warn about orphan sections
(Previous patch set was reverted due to issue with priv_stack.
 Resubmitting after fixing the faults caused by priv_stack.noinit
 not at the end of RAM.)

This adds a linker flag and necessary changes to linker scripts
so that linker will warn about orphan sections.

Relates to #5534.

Fixes #10473, #10474, #10515.
