Re: Status of PCI-PCI bridge on UMAX S900

it seems like someone was confused about the meaning of the 'interrupts'
property when they wrote prom.c.  its basically the number of interrupts
supported by this pci device.  interpret_dbdma_props() also has the
same confusion, so the following would be a more complete patch to
prom.c.  note that it checks to see if a pci node has an interrupt
property before assigning one, otherwise devices on the far side of
a pci bridge (that shares interrupts) would be assigned interrupts
when they dont need them.
Today I tried your patch. Well, I breaks the hole interrupt stuff.
Now, even Mesh has trouble with interrupts (kernel crash), the
console=ttyS0 doesn't work so no output from the booting ...
The "interrupts" property can have various meanings depending on the OF
version, I suggest you don't mess with it. Just check that if you find no
AAPL,interrupts, and that pmac_newworld == 0, then look for parent
AAPL,interrupts.
