10 * Zephyr build for nRF9160 with ARM TrustZone-M support,

12 *
13 * Secure image will be placed, by default, in flash0
14 * (or in slot0, if MCUboot is present).
15 * Secure image will use sram0 for system memory.
16 *
17 * Non-Secure image will be placed in slot0_ns, and use
18 * sram0_ns for system memory.
19 *
20 * Note that the Secure image only requires knowledge of
21 * the beginning of the Non-Secure image (not its size).
