[Bug 2026588] [NEW] [SRU] Copy OpenSBI 1.3 to Jammy and Lunar

[Heinrich Schuchardt]

Public bug reported:

[ Impact ]

We provide an image for the StarFive VisionFive 2 board. Upstream U-Boot
now provides support for the board but it requires OpenSBI 1.3. We
should strive to put a current U-Boot onto our preinstalled image.

[ Test plan ]

* Rebuild current u-boot package in ppa against new OpenSBI and test running Ubuntu 22.04/23.04 on QEMU, SiFive HiFive Unmatched, and PolarFire Icicle Kit with this U-Boot.
* Use a rebuilt u-boot-nezha package to boot the Nezha D1.
* Run apt-get update, apt-get install, and execute an application.
* Run snap install and execute an application.

[ Where problems could occur ]

OpenSBI is only used directly when running a RISC-V emulation in QEMU
with the bios parameter.

For all real hardware OpenSBI is built into U-Boot SPL. So getting
OpenSBI onto boards will require a rebuild of U-Boot.

Theoretically upgrading OpenSBI could

* stop RISC-V boards from booting
* cause failures when the operating system calls into OpenSBI
* cause failures when OpenSBI emulates missing instructions.

[ Other Info ]

Upgrading to the same OpenSBI 1.3 that we use in Mantic instead of
applying selected patches to 22.04/23.04 is easier to maintain in the
long run.
