Subject: PCI interrupt assignment on sequoia board

Hi,

I noticed that Josh's 'for-2.5.25' does not assign PCI interrupts correctly:

bash-3.00# lspci -v
00:00.0 Class 0680: 1014:027f
        Subsystem: 10e8:cafe
        Flags: bus master, medium devsel, latency 0, IRQ 16
        Memory at <unassigned> (32-bit, prefetchable)
        Capabilities: [58] Power Management version 2

00:0a.0 Class 0b20: 1014:027f	(this is a PPC440EPx PCI target board in a sequoia PCI slot)
        Subsystem: 12fe:0441
        Flags: bus master, medium devsel, latency 128, IRQ 16
        Memory at 0000000180000000 (32-bit, prefetchable) [size=64M]
        Memory at 0000000184000000 (32-bit, prefetchable) [size=16M]
        Capabilities: [58] Power Management version 2

00:0c.0 Class 0200: 168c:0013 (rev 01)
        Subsystem: 14b7:0a60
        Flags: bus master, medium devsel, latency 128, IRQ 16
        Memory at 0000000185000000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2

bash-3.00# uname -a
Linux sequoia 2.6.24-rc6-g78994e24 #5 Wed Jan 9 16:22:31 CET 2008 ppc ppc ppc GNU/Linux

All interrupts are '16'. But I expected 67 as correctly stated in the device tree.
This test has been made with the uboot wrapper code.

Any idea?

Matthias
