Title:
  OpenSBI 0.8 backport

Status in opensbi package in Ubuntu:
  Fix Released
Status in opensbi source package in Focal:
  Fix Released

Bug description:
  OpenSBI 0.8 backport

  [Impact]

   * OpenSBI is used to create RISC-V images for various boards and to
  boot RISC-V virtual machines.

   * 0.7 & 0.8 add support for more hardware, but are otherwise
  backwards compatible.

   * qemu/virt file location got moved to generic, add backwards
  compatible symlink for it, to avoid breaking any stable users.

  [Test Case]

   * Boot cpc hirsute cloud image using opensbi fw loader from qemu/virt
  and generic location

  [Where problems could occur]

   * OpenSBI adds more hardware features, which some kernels might not
  be compatible with. Given how quickly the platform evolves newer
  OpenSBI is better. But things may fail to boot, or missbehave - i.e. a
  VM that used to boot and not work, will now boot and not work
  differently =) for example there are shutdown/poweroff/reboot issues
  with any sets of opensbi & Ubuntu kernels.
