I think it's more difficult than that. We talked about this during the summit
(there's a similar problem with the alix.2c3 and eth2/usb interrupts), and
Marc said that in addition to a change like this patch, we need to make the
change in the VSA...

I'm not sure how that would work. Ideally this stuff would be board-specific;
can we adjust the cs5536 internal interrupts in the VSA somehwo during
coreboot build?
