This series allows to automatically export the registered bbu handlers
to fastboot. This way barebox can be updated via fastboot without much
preparation. Setting the following variables will be enough:
nv usbgadget.fastboot_function=""
nv usbgadget.autostart=1
nv usbgadget.fastboot_bbu=1
The exported partitions are then named bbu-<bbuname>.
example:
# fastboot -i 0x1d6b getvar all
< waiting for any device >
(bootloader) version: 0.4
(bootloader) bootloader-version: barebox-2017.09.0-00121-g9fde4fe832-dir
(bootloader) partition-size:bbu-mmc: 000c0000
(bootloader) partition-type:bbu-mmc: basic
