Ha! This aged well! I finally managed to switch us away from using
u-boot (at least on the classic images, Ubuntu Pi for Server and
Desktop, though not on Core) during the Groovy (20.10) release, but
somehow managed to forget about closing this bug!
** Changed in: flash-kernel (Ubuntu)
Sorry, we'll be sticking with u-boot for the foreseeable future. Partly
this is because it keeps things (somewhat) consistent between the core
and classic images, but also keeps things consistent between RPi and
Ubuntu images for other embedded platforms. Were we to remove u-boot
from the RPi
