this information applies to any board and it seems like good information to have but to have it globally rather than multiple times in different boards - which also means it's easier to maintain updating once then X times in boards - thoughts @kartben ?

+1 -- would suggest adding an rst "snippet" boards/common/doc and the .. literalinclude it wherever needed

==================

The sysbuild makes possible to build and flash all necessary images needed to
bootstrap the board.

To build the sample application using sysbuild use the command:

.. zephyr-app-commands::
:tool: west
:zephyr-app: samples/hello_world
:board: ek_ra8p1/r7ka8p1kflcac/cm85
:goals: build flash
:west-args: --sysbuild
:gen-args: -DSB_CONFIG_BOOTLOADER_MCUBOOT=y

By default, Sysbuild creates MCUboot and user application images.

Build directory structure created by sysbuild is different from traditional
Zephyr build. Output is structured by the domain subdirectories:

.. code-block::

build/
├── hello_world
| └── zephyr
│ ├── zephyr.elf
│ ├── zephyr.hex
│ ├── zephyr.bin
│ ├── zephyr.signed.bin
│ └── zephyr.signed.hex
├── mcuboot
│ └── zephyr
│ ├── zephyr.elf
│ ├── zephyr.hex
│ └── zephyr.bin
└── domains.yaml

.. note::

With ``--sysbuild`` option, MCUboot will be rebuilt and re-flashed
every time the pristine build is used.

To only flash the user application in the subsequent builds, Use:

.. code-block:: console

$ west flash --domain hello_world

For more information about the system build please read the :ref:`sysbuild` documentation.

You should see the following message in the terminal:

.. code-block:: console
