But we do have P1022DS board support, and my understanding is that part of
the function of U-Boot is to prepare the board so that it can be used by
Linux, or whatever OS it boots.

Besides, there's tons of hardware that is not supported by U-Boot but must
be initialized by U-Boot anyway.

Well, now we're talking about a very old issue that always raises
disagreement -- exactly what should U-Boot be doing vs. Linux.  And this is
something that changes over time.  For example, QE pin muxing used to be
done in U-Boot, but now it's done in Linux.  Well, except for the QE
features that U-Boot uses.  In that case, it's done in U-Boot *and* Linux.
