As 5.12 has been released, is this possible to consider having this new machine in the next release?

All changes are contained under arch/m68k and protected by the CONFIG_VIRT flag. This should not
have any impact on the other m68k machines. In any case, I'll be able to maintain the machine and
fix any problem.

Thanks,
Laurent
