Older PARISC for example have PCI busses hanging off gecko. I do agree with you for the general case. So systems whose root level bridges are 'normal' should reflect this and I guess others should attach them to the relevant bus. Over time it seems that PCI is going to become a secondary bus like ISA did as well. In fact it already has in many ways, its just things like VLINK and the Intel hub busses look like PCI to us - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
