Bug Description
OpenSBI 0.9 backport to Focal
[Impact]
* OpenSBI is used to create RISC-V images for various boards and to boot RISC-V virtual machines.
* Our current 0.8 release lacks a patch for CPU erratum CIP-1200 described in Errata_
* Bugs in OpenSBI that may lead to crashes have been resolved in v0.9.
[Test Case]
* Build U-Boot with new OpenSBI version and boot Focal images with this U-Boot installed.
[Where problems could occur]
* Parts of the OpenSBI code where restructured, new SBI extensions were added. Bugs in the modified code might lead to failure to boot, reboot, poweroff or might lead to crashes.
