Add a quirk to just ignore the FPGA. This is based on the following patch from Andy & York: http://ozlabs.org/pipermail/linuxppc-dev/2007-February/032042.html Signed-off-by: Kumar Gala --- diff --git a/arch/powerpc/platforms/85xx/mpc85xx_cds.c b/arch/powerpc/platforms/85xx/mpc85xx_cds.c index 9b559ebc66f8..71200bdce05a 100644 --- a/arch/powerpc/platforms/85xx/mpc85xx_cds.c +++ b/arch/powerpc/platforms/85xx/mpc85xx_cds.c @@ -108,6 +108,16 @@ static void __init mpc85xx_cds_pci_irq_fixup(struct pci_dev *dev) } } +static void __devinit skip_fake_bridge(struct pci_dev *dev) +{ + /* Make it an error to skip the fake bridge + * in pci_setup_device() in probe.c */ + dev->hdr_type = 0x7f; +} +DECLARE_PCI_FIXUP_EARLY(0x1957, 0x3fff, skip_fake_bridge); +DECLARE_PCI_FIXUP_EARLY(0x3fff, 0x1957, skip_fake_bridge); +DECLARE_PCI_FIXUP_EARLY(0xff3f, 0x5719, skip_fake_bridge); + #ifdef CONFIG_PPC_I8259 #warning The i8259 PIC support is currently broken static void mpc85xx_8259_cascade(unsigned int irq, struct irq_desc *desc)
