Hi

I don't see how the PCI irq mapping is done in the denx CVS. I know on
the lite5200 hardware, INTA is connected to IRQ0 and it's the only
connected but I don't see how they are linked in the software. I
though that was the role of the ppc_md.pci_map_irq function but I
don't see any defined ? Is there a default behavior ? Or is it just
luck ;)

Thanks,
