Title:
  missing device-tree fixups

Status in grub2 package in Ubuntu:
  Fix Released

Bug description:
  When U-Boot loads a device-tree it makes fixups like adjusting the
  memory size before booting into Linux. When GRUB loads a device-tree
  these fixups are missing. On RISC-V the Linux kernel expects the
  property /chosen/boot-hartidproperty in the device-tree which is set
  during fixups.

  There are two solutions to this:

  Either always load the device-tree in U-Boot or call the
  EFI_DT_FIXUP_PROTOCOL implemented in U-Boot. Calling the protocol
  seems to be the better solution.
