Cascade handling is changing with my genirq port. It will be easy to
adapt though. Same comments howveer, you should have a device-
tree node
for the 8259 (under an ISA bridge, those shall really be in the
device-tree). In general, on-board bridges should be in the
device-tree,
only slots or standardly routed child PCI devices need not.
Can you send me an example?
I'll try to dig something. Power3 at least has MPIC<->8259 cascade, as
do some IBM blades when running bare metal kernels.
On the blades, the 8259 isn't cascaded to the MPIC. And we disable
it completely anyway ;-)
