This adds support for the 6.1 CIP-Kernel. As the 5.8 kernel is planned
to be meaintained until 2023 I added additional options for those
starting new projects.
Also update the documentation to reflect the current EOL date instead of
just stating that it will be meaintained for 10 years.

Thanks for the patch. My question is what does the CIP 6.1 kernel
brings that the "official stable 6.1" doesn't bring? Indeed official
6.1 is still maintained by GKH until Dec 2026. I do understand the
value of CIP when it picks up maintenance after the "main" kernel
community gives up, but for something still maintained?

This question in fact also applies to the current CIP 5.10 kernel we
already have, as 5.10 is still maintained upstream, also until Dec 2026.

Wouldn't it make more sense to have the CIP 4.4 kernel in Buildroot,
for which there is no longer any maintenance upstream, and therefore
for which the CIP effort does make sense?

Thanks a lot for your feedback,

Thomas

Since no feedback was provided to this question, I marked the patch as
Rejected. We can of course revisit if additional feedback/argumentation
is provided, for sure!

Best regards,

Thomas
