This is the only item remain before I generate an patch with just the
memory controller. Most of the code that I see are actually an
interrupt controller HW. As it is just an interrupt mask and status
registers, is there an example in Linux that I can model after? Also,
I am not quite convince as to why we can't just share the interrupt
and request it by each memory controller?
