Switching partitions is usually not some isolated feature, but part of a software update and reliable fall back configuration. In U-Boot, it is usually found in combination with the boot counter feature; in Linux, it usually requires support of a (hardware) watchdog. Once you reached that point, you probably want to look at the swupdate [1] project and read it's documentation...
