boards: intel_adl: Reuse efi_boot part in docs

      A Zephyr EFI image file named :file:`zephyr.efi` is automatically

      created in the build directory after the application is built.

Preparing the Boot Device

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

Booting the Alder Lake N CRB Board using UEFI

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

Prepare a USB flash drive to boot the Zephyr application image on

an Alder Lake CRB board.

#. Format the USB flash drive as FAT32.

   On Windows, open ``File Explorer``, and right-click on the USB flash drive.

   Select ``Format...``. Make sure in ``File System``, ``FAT32`` is selected.

   Click on the ``Format`` button and wait for it to finish.

   On Linux, graphical utilities such as ``gparted`` can be used to format

   the USB flash drive as FAT32. Alternatively, under terminal, find out

   the corresponding device node for the USB flash drive (for example,

   ``/dev/sdd``). Execute the following command:

   .. code-block:: console

      $ mkfs.vfat -F 32 <device-node>

   .. important::

      Make sure the device node is the actual device node for

      the USB flash drive. Or else you may erase other storage devices

      on your system, and will render the system unusable afterwards.

#. Copy the Zephyr EFI image file :file:`zephyr/zephyr.efi` to the USB drive.

Booting the Alder Lake CRB Board

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

Boot the Alder Lake CRB board to the EFI shell with USB flash drive connected.

#. Insert the prepared boot device (USB flash drive) into the Alder Lake CRB board.

#. Connect the board to the host system using the serial cable and

   configure your host system to watch for serial data.  See

   `INTEL_ADL`_ website for more information.

   .. note::

      On Windows, PuTTY has an option to set up configuration for

      serial data.  Use a baud rate of 115200.

#. Power on the Alder Lake CRB board.

#. When the following output appears, press :kbd:`F7`:

   .. code-block:: console

      Press <DEL> or <ESC> to enter setup.

#. From the menu that appears, select the menu entry that describes

   that particular EFI shell.

#. From the EFI shell select Zephyr EFI image to boot.

   .. code-block:: console

      Shell> fs0:zephyr.efi
