Can I configure the recovery-reboot application for a dual boot system?

I want to configure a dual boot system with two .swu firmware images.
One is actual (running) and one is standby. The update command should run from the actual image and replace the standby image. This new image changes to actual and the old actual changes to standby.
U-Boot must know which image is actual and which one is standby (and boot the actual).

You can create multiple partitons place different images in different partitions and then use u-boot variables to point boot process to correct partition.
