[PATCH] sbc8548: fix incorrect PCI-X and PCI interrupt map

From: Jeremy McNicoll <hidden>
Date: 2008-03-08 07:55:33

The following patch allows interrupts to occur on the
sbc8548. Currently PCI and PCI-X devices get assigned an IRQ
but the interrupt count never increases.  This solves the
problem and adds PCI support as well.
