You can just dd out the appropriate u-boot from a running device with
the command below and then just reboot. You can grab newer Fedora
u-boot builds from koji [1] to use those.

sudo dd if=/usr/share/uboot/$TARGET/u-boot-sunxi-with-spl.bin
of=$MEDIA bs=1024 seek=8; sync

There's work being done on some utilities to make this easier to do.
