I forgot to mention I deliberately chose to keep the Altera
timer model in the tree, since it looks like a re-usable
IP component.
But if it is not used anymore by any machine, this will happily
bitrot, won't it? I think I'd rather remove it, too ... maybe in a
separate patch, so that in case somebody later needs it again, it can
be restored by simply reverting the patch again.
It is related to dynamic machines, how do we decide what components
to remove once there? I suppose we'd need to deprecate every single
component, like ALTERA_TIMER. But we are not yet generating dynamic
machines, so for now we can consider ALTERA_TIMER part of Nios II
sysemu removal. I like your idea of removing it as a separate patch.
Even if we switch to dynamic machines one day, the devices still need to
be somehow used and tested in the CI, e.g. by scripts that assemble a
machine dynamically. If there's a device that is never used at all, we
can also simply remove it until someone needs it again, I think.
Fair enough :)
