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

[Alexandre Ghiti]

[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).

Looks good; I've uploaded this to jammy-proposed (minus the ~ppa0 suffix obviously), and targetted the bug to jammy. Could you remove ubuntu-sponsors from the notification list? Thanks!

[Steve Langasek (vorlon)]

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.

And on the Nezha board with an image that was built with this version, the image booted fine.
