Betreff: Re: [PATCH 2/5] powerpc: Generic device
I think I throw away the IDE controller node for now, as libata just reads
the PCI register settings (progif) and I guess the IDE subsystem will do
the same in the future.
Well... if all AmigaOne use a 8259, they probably use the same interrupt
routing except for PCI slots. In which case, I

Yes, all AmigaOne boards have physical PCI slots (at least 1). The different
interrupt routing wasn't a problem so far, as the firmware writes the IRQ
number
to the interrupt line register of every PCI device.
The code in the kernel that retreives the interrupt that way is clearly
marked as

This device tree does not provide the correct CPU name, as various CPU
models and revisions are used in AmigaOnes. Also the PCI root node does
not contain a interrupt mapping property, as all boards have different
interrupt routing. However the kernel can do a 1:1 mapping of all PCI
interrupts, as
