[Bug 1978923] Re: SRU flash-kernel to add support for RISC-V boards

[Steve Langasek]

Hello Alexandre, or anyone else affected,

Accepted flash-kernel into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/flash-
kernel/3.104ubuntu11 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  SRU flash-kernel to add support for RISC-V boards

Status in flash-kernel package in Ubuntu:
  New
Status in flash-kernel source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  The image for the StarFive VisionFive and the Nezha boards will be
  available in 22.04.1: in order to be able to boot using UEFI, we need
  flash-kernel to install the DTBs to the right location for GRUB to
  load, so we need to add those boards to the flash-kernel database.

  [Test Plan]

  I tested the version that built here [1] on the VisionFive board, and
  flash-kernel worked correctly:

  [Where problems could occur]

  The changes are board-specific so it should not alter the behaviour on
  other boards and unfortunately, I tried flash-kernel on a non-working
  kernel as the kernel team is still working on it, but the changes are
  straightforward enough.

  [Other Info]

  I added support for the LicheeRV board although not officially supported, but as it works well with our current kernel, we'd better have it available.
  Note that I dropped the ~22.04.1 suffix and moved to 3.104ubuntu11 as @waveform has just uploaded 3.106ubuntu1 into kinetic (which already contains the support for those boards).
