I'm interested in starting the secondary cpus on mainline. It seems that
that "thead,reset-sample" is already implemented in upstream OpenSBI in
lib/utils/reset/fdt_reset_thead.c and the issue is getting the
dt-binding accepted. Is that correct?
It looks like you've tried to restart the discussion on the DT list [1]
so I hope that the DT maintainers will give their perspective.
Thank you,
Drew
