Hello,
is there any recommended list of single board computers for GuixSD?
I read FSF site (1) but it was last updated in June 2015.
Is there any site like h-node (2) but for SBCs?

I wanted to buy banana-pro pi (3) but i don't know if it is going to work under GuixSD or other free distribution.
Other possible SBCs (4 5 6), their websites states they are open source but i don't know if they are free.

Thanks,
