Title:
  Support tryboot's A/B booting on Raspberry Pi

Status in flash-kernel package in Ubuntu:
  Fix Released

Bug description:
  The Raspberry Pi's tryboot mechanism [1] permits an A/B booting
  structure that permits fallback in the event of bad boot assets (or a
  bad boot configuration). We already substantially patch flash-kernel
  for the Raspberry Pi (to permit moving an image between boards); we
  should adjust the existing "pi" method (or add a new "pi-something"
  method) to write new boot assets to a temporary location from which
  they can be tested with the "tryboot" mechanism.
