No problem, no need to hurry!

I've researched a little in the mean time and found out that other projects
DO have automated u-boot installation, for example:

https://github.com/buildroot/buildroot/blob/master/board/olimex/a20_olinuxino/genimage.cfg

So we could leave this stuff mostly to them - although it would mean
we'd only support boards they support.

It would make us lose support for these for now:

* qemu_arm_vexpress
* qemu_mips64el_malta
* banana-pi-m2-ultra
* nintendo-nes-classic-edition
* novena
* cubieboard
* puma-rk3399

So we'd have to upstream support for those[1] - and also have a fallback in the
mean time maybe.

A very minimal WIP patch for that is attached.

What it does is install a "genimage.cfg" which describes how to install u-boot for
the current board into the derivation of u-boot.

Do we want to proceed like that?

Should I move load-u-boot-config into a new guix/build/u-boot.scm ? Or how
do I get it into the build side without rebuilding the world?

[1] I added banana-pi-m2-ultra in my local buildroot checkout by creating 3 short
text files, so it's not that bad.
