Title:
  u-boot unmatched dtb does not match kernel dtb

Status in u-boot package in Ubuntu:
  New

Bug description:
  u-boot unmatched dtb does not match kernel dtb

  We have reverted u-boot-menu upload and stopped using kernel provided
  dtbs, because that was preventing booting hirsute images under qemu.
  As dtb generated by qemu should be used, and there is no kernel
  provided dtb for qemu platform.

  This resulted in unamtched board using dtb provided by u-boot, instead
  of loading and using dtb provided by the kernel builds.

  There are differences between u-boot & kernel dtbs that potentially
  break compat.

  There are two ways of fixing this:

  1) bring uboot dtb in-line with the kernel dtb

  2) fix qemu uboot to not load dtbs from disk, even when extlinux.conf
  asks to; and resume loading the matching kernel dtb from disk

  Option 1) sounds easier for release.

  The diff between u-boot's unmatched dtb & kernel provided dtb is at
