Hi there.
Im working on some SoC type devices attached to the system bus of my ARM
devboard in an isa-like way.
The devices are small SoC (System On Chip) types, with one IRQ routed to
the half dozen (sub)devices on board the SoC.
I just thought of a 'third way'.
let IRQchips have their own struct irq_desc and have subdevice IRQs
start from 0.
since those IRQs can only be raised by the parent chip I think this
ought to work, and would eliminated the problem of a fixed size irq array...
