Re: [pci] why the address are grey coded?

Besides - it's always good design when it makes sense. Higher clock rates
without carry propagate delays, fewer transitions per clock resulting in
lower power and less system noise.

	The addresses are grey coded because it's an asynchronous fifo design.
	Normal binary counter comparison is only good for synchronous fifo designs.
