MCUboot and NSIB

If you are new to bootloaders and Device Firmware Upgrade (DFU), see the Quick start guide. If you have worked with them before and prefer a standard bootloader setup in your application, read the Partitioning device memory documentation page. Following that, you can add an immutable bootloader.
