/*
 * Default Flash planning for bl5340_dvk CPUAPP (Application MCU).
 *
 * Zephyr build for BL5340 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).
