Zigbee FOTA implementation

Hi,

I think you can take look at the board and child image configurations in the Zigbee: Light switch samples to see how they are configuring the FOTA with ext flash using our onboard flash IC.

The FOTA samples usually set this "chosen" in the overlay as https://github.com/nrfconnect/sdk-nrf/blob/e6c201742e685591dbc7416e3239fcd45e095e07/samples/zigbee/light_switch/child_image/mcuboot/boards/nrf5340dk_nrf5340_cpuapp_fota.overlay It's worth to try.

Yes, we have an overlay for cpu_app that includes the new flash.

We have confirmed that we can use this flash on the application code prior to attempting to include the configurations needeed to include Zigbee FOTA & MCUBoot.

```

&qspi {
 status = "okay";
 pinctrl-0 = <&qspi_default>;
 pinctrl-1 = <&qspi_sleep>;
 pinctrl-names = "default", "sleep";
 mx25r16: mx25r1635f@0 {
 compatible = "nordic,qspi-nor";
 reg = <0>;
 size = <16777216>;
 /* MX25R64 supports only pp and pp4io */
 writeoc = "pp4io";
 /* MX25R64 supports all readoc options */
 readoc = "read4io";
 sck-frequency = <8000000>;
 label = "MX25R16";
 jedec-id = [C2 28 15];
 sfdp-bfp = [
 e5 20 f1 ff ff ff ff 00 44 eb 08 6b 08 3b 04 bb

 };
};

Hi,

Do you create a overlay like this nrf5340dk_nrf5340_cpuapp.overlay and include the content of https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L173-L198 for your external flash? If not, please do it.

For the config of nRF5340 Zigbee FOTA, please refer to:
https://github.com/nrfconnect/sdk-nrf/blob/e6c201742e685591dbc7416e3239fcd45e095e07/samples/zigbee/light_switch/boards/nrf5340dk_nrf5340_cpuapp_fota.conf
