v1 was here:
https://lore.barebox.org/barebox/20210215102740.30418-1-a.fatoum@pengutronix.de/#r
https://lore.barebox.org/barebox/20210215103704.32537-1-a.fatoum@pengutronix.de/

v1 -> v2:
  - rebase on top of new bthread API
  - drop blocking fallback implementation; we now have bthreads
    everywhere
  - reuse $global.system.partitions instead of creating even more
    autostart variables
  - fix assert_command_context to actually do what the commit message said

Ahmad Fatoum (4):
  bthread: implement basic Linux-like completion API
  slice: reschedule bthreads doing File I/O in command context
  usbgadget: refactor usbgadget_register to accept array
  usbgadget: add support for USB mass storage gadget
