I'll experiment with such, likely later today, thanks.

Is there someplace that notes such a need, some directions
to follow?

Right now the only places that seem to fit would be
adding some "how to use this u-boot" notes to the likes
of:

/usr/local/share/u-boot/u-boot-*/README

I supposed where there is someplace somewhat
analogous to:

/usr/local/share/rpi-firmware/

that it might be a place to have such notes.
