i'm not sure how i got to this point - i tried to get it working 6 months
ago after the switch to efi, and Matthieu's mail prompted me to look at it
again. I probably did an environment reset back then. I also needed to
recover to a working u-boot back then, by doing
https://boundarydevices.com/unbricking-nitrogen6x-sabre-lite-i-mx6-board/
2 days ago i upgraded to the u-boot in snaps (u-boot-arm-2017.01).
