Title:
  OpenSBI: system reset support missing for HiFive Unmatched

Status in opensbi package in Ubuntu:
  New

Bug description:
  With our current images the Linux poweroff and reboot commands fail.
  Same for U-Boot.

  https://github.com/sifive/meta-sifive/tree/2021.06/recipes-
  bsp/opensbi/files/unmatched contains a series of patches to provide
  the system reset extension in OpenSBI.

  http://lists.infradead.org/pipermail/opensbi/2021-July/001243.html is
  starts a series of patches to upstream a system reset extension
  implementation.

  Suggested actions:

  Build OpenSBI with one of the two series and check what additional
  changes in Linux and U-Boot might be needed to get working poweroff
  and reboot.

  Best regards

  Heinrich
