This can be reproduced like so:

This is the dreaded “circular top-level references” case: to load
firmware.scm, you need to (indirectly) load bootloaders.scm; but to load
bootloader.scm, you need to be able to look up ‘crust-pine64-plus’,
which is then unbound.

Fixed in 0ab46ef3f9719f03d9b191a16e5aa91619e95451 by introducing
promises.

BTW, we should probably keep ‘make-u-boot-sunxi64-package’ private, no?

Thanks,
Ludo’.
