I don't think full-on option ROMs with configuration menus are
something we care about for EBBR-style implementations.
What could be useful is things like shim - a simple driver installing
a protocol that lets other applications running at boot-time access
it. But I think that is already (mostly?) supported.

If someone at a later date decides that they want to support option
ROMs, basically using U-Boot for an SBBR implementation, that will
come with additional work required for the menu support. And should be
possible to configure out at build time for users who don't want it.
