The 'revert' mechanism in direct-xip is similar to the one in swap mode. It requires the trailer magic to be added to the signed image. When a reboot happens without the image being confirmed at runtime (without the image_ok flag being set), the bootloader considers the image faulty and erases it. After this it will attempt to boot the previous image instead. The images can also be made permanent (marked as confirmed in advance) just like in swap mode.
