This is all you need to have a running system. Not that it would be
of any use, of course.

I think you put the cart before the horse. It's not the boot loader
that determines which peripherals are needed, but your application.
U-Boot is flexible enough to do with what's available.
Of course, an UART for a serial console port is pretty useful, as is
an Ethernet interface because it greatly accelerates the development
cycle. Or some flash memory to save your images and envrionment
Bot none of this is strictly necessary.

Nobody trips over mountains. It is the small pebble that causes you
to stumble. Pass all the pebbles in your path and you will find you
have crossed the mountain.
