Can you elaborate what the typical kernel upgrade schedule for
these boards?
Note that for the debate about dropping the machines from future
kernels, it does not really matter how many remaining users there
are or how many boards get sold. The only question is whether
someone is still planning to provide upgrades to kernels later
than linux-6.3 in the future.
It sounds like there are commercial requirements for validating
and distributing kernel upgrades (in addition to hobbyist uses), so
I would expect that whoever is paying for the upgrades has a clear
plan for how much longer they are going to do that, or at least
a some idea of how many of the previous LTS kernels (5.10, 5.15,
6.1) ended up actually getting shipped to users.
It may be worth pointing out that the official webpage for
the MPC8313ERDB board in the example only lists a hilariously
outdated BSP kernel based on a patched linux-2.6.23 release,
so maybe the marketing team can change that to point to the
latest validated LTS kernel instead.
