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...
