Besides that, SMI HW also does: - Prioritize/arbitrate memory requests between different ports & larbs. - Bandwidth limiter - Performance monitor I think drivers/memory make more sense. I can't find info about drivers/memory in MAINTAINERS. Can this go through ARM SoC tree if we put SMI driver there?
