CPU and RAM.

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
variables, etc.

Bot none of this is strictly necessary.

Best regards,
