Recent Linux kernels are accessing the PCI device in slot 0 that represents the PCI host bridge. This causes ppc4xx_pci_map_irq() to return -1 which causes an assert() later: hw/pci/pci.c:262: pci_bus_change_irq_level: Assertion `irq_num >= 0' failed. Thus we should allocate an IRQ line for the device in slot 0, too. To avoid changes to the outside of ppc4xx_pci.c, we map it to the internal IRQ number 4 which will then happily be ignored since ppc440_bamboo.c does not wire it up. With these changes it is now possible again to use recent Linux kernels for the bamboo board.
