Alberto Escolar Piedras 6c38bc8ec4 boards native_posix: Remove twister support
native_posix is being removed as it has reached its end of life in 4.2,
after being deprecated since 4.0.

Remove the twister support for native_posix[//64] and therefore all
references to them from the testcases and samples yamls, so twister
does not error out.

.. zephyr:code-sample:: eeprom
   :name: EEPROM
   :relevant-api: eeprom_interface

   Store a boot count value in EEPROM.

Overview
********

This sample demonstrates the :ref:`EEPROM driver API <eeprom_api>` in a simple boot counter
application.

Building and Running
********************

In case the target board has defined an EEPROM with alias ``eeprom-0`` the
sample can be built without further ado. This applies for example to the
:ref:`native_sim` board:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/eeprom
   :host-os: unix
   :board: native_sim
   :goals: run
   :compact:

Otherwise either a board specific overlay needs to be defined, or a shield must
be activated. Any board with Arduino headers can for example build the sample
as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/eeprom
   :board: nrf52840dk/nrf52840
   :goals: build
   :shield: x_nucleo_eeprma2
   :compact:

For :zephyr:board:`gd32f450i_eval` board. First bridge the JP5 to USART with the jumper cap,
Then the sample can be built and executed for the  as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/eeprom
   :board: gd32f450i_eval
   :goals: build flash
   :compact:

Sample Output
=============

.. code-block:: console

    Found EEPROM device "EEPROM_M24C02"
    Using eeprom with size of: 256.
    Device booted 7 times.
    Reset the MCU to see the increasing boot counter.
