How many of them are also license:gpl* though? That would hopefully
reduce the scope somewhat, or maybe even significantly...
If "guix package --search= ..." could be extended to to also search
other fields, e.g. license: and dependencies: ... it might not be so
difficult a search.

For what it's worth, I did do local builds of all the current u-boot-*
targets in guix with openssl removed from inputs, and the only one that
failed to build without openssl was u-boot-tools.

I think it is using it for generating and verifying rsa signatures, and
probably other similar basic things. So far I had only thought about
gnutls, but if gcrypt or nettle are other options, then so much the
better.
I briefly looked at gnutls's openssl compatibility layers, but it didn't
seem to implement sufficiently similar include files, which is largely
all that it is doing.

I did bring it upstream a little over a year ago, and the response was
pretty much to rewrite it with gnutls, and I pointed out the most likely
files that needed updating:
https://lists.denx.de/pipermail/u-boot/2017-November/312483.html
https://lists.denx.de/pipermail/u-boot/2017-December/313616.html
https://lists.denx.de/pipermail/u-boot/2017-December/313742.html
I suspect it's pretty much a "patches accepted" sort of scenario.
