In order to boot on ARM-based machines (i.e. banana pi), guix needs to
use u-boot. u-boot-allwinner-bootloader should be in (gnu bootloader u-
boot). 
Since every ARM computer has different hardware, you may need to make a
new bootloader and u-boot package for your banana pi M1. You can try
greping the sources for "bananapi-m2-ultra" and making corresponding
packages for bananapi-m1. I'm afraid I can't help you if that doesn't
work though.
I have been trying to make my banana pi m2u run the guix system for
several weeks now without success because it isn't very well
documented. The installer disk image I generated doesn't work when I dd
it to the built-in emmc (bug report pending). If the disk image you are
generating doesn't work, try using guix on armbian to bootstrap the
system as described in the tutorial at <
https://guix.gnu.org/blog/2019/guix-on-an-arm-board/> and make sure the
bootloader and / refer to separate partitions.
