Will INTERRUPT_CONTROLLER confuse people? There is only one GIC redistributor
(some people regard it as interrupt controller) in ARM system, if we use
INTERRUPT_CONTROLLER people will regard it as multi-redistributors in the
system, I think GIC_CPU_INTERFACE would be better, what do you think?

I think you meant to say "one GIC _distributor_" (GICD) instead of
redistributor (GICR).
ACPI5.1 only describes one GICD per system, but we can most certainly
describe multiple GICRs.
For multi-cpu systems, you'll definitely see multiple GIC redistributors.

Yes, you are right, thanks for pointing it out, I think I need more coffee :)

Thanks
