In the embedded world there are many vendors of custom boards, so
such a directory might become very big, even if there is only one
file per board. Also I like the idea that I see all affected boards at
first sight when I change something in lets say the mpc52xx interrupt
controller.
I don't know how this performs in the 'big computer world' where vendors
combine a cpu with different chipsets. In the SoC world where every SoC
has the very same interrupt controller and device layout this behaves
quite well. Things become very orthogonal with per SoC directories.
(I'm more familiar with arm, where directories are organized this way,
so you might want to look at arch/arch/mach-* to see what I mean)
