Help is always welcome.

But the point is that the companies who build and sell that stuff have
the responsibility to take care of it and not just dump their crap into
the kernel and then expect that someone else will take care of it for
free.

If SiFive pays you or your employer to provide that service that's fine,
but you doing it on your on [dt]ime to proliferate the carelessness of
those who profit from it is just wrong.
