In general, we don't really like to have too much version selection for
components, because it makes the maintenance difficult, and it is also
more difficult for users as they have to know which version to use.

However, for the specific case of this firmware package, I don't really
see any other option than what you're proposing.

One question is: how does it work if one wants to use the upstream
Linux kernel?

Best regards,

Thomas
