* Default Flash planning for nrf5340dk_nrf5340 CPUAPP (Application MCU).
*
* Zephyr build for nRF5340 with ARM TrustZone-M support,
* implies building Secure and Non-Secure Zephyr images.
*
* Secure image will be placed, by default, in flash0
* (or in slot0, if MCUboot is present).
* Secure image will use sram0 for system memory.
*
* Non-Secure image will be placed in slot0_ns, and use
* sram0_ns for system memory.
*
* Note that the Secure image only requires knowledge of
* the beginning of the Non-Secure image (not its size).
