Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0
Move to CMake 3.20.0.

At the Toolchain WG it was decided to move to CMake 3.20.0.

The main reason for increasing CMake version is better toolchain
support.

Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

EEPROM Sample
#############

Overview
********

This sample demonstrates the EEPROM driver 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_posix` board:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/eeprom
   :host-os: unix
   :board: native_posix
   :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:

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 inceasing boot counter.
