One of reasons why only a single image be included is that I didn't
see any strong reason to do so because U-Boot already has an archive
format of multiple images, named FIT. I wanted to utilize the existing
framework which is widely used on U-Boot and the current implementation
of FMP supports this format.
It seems to be just enough.

Do you have any useful use case of multiple images?
