I think we should adapt to whatever U-Boot provides for installation.
(I installed it years ago on a plug computer but forgot all the
details.)

Not everything is in separate files I think, but ‘git rebase -i’ or
similar should facilitate the operation.

The “build side” is the (gnu build …) and (guix build …) modules: they
contain code that is executed as part of build processes, or at run
time.

The “host side” is the rest, which contains package declarations, OS
declarations, service declarations, and code that drives the compilation
of all that.

(See “G-Expressions” in the manual for a discussion of this.)
