Unfortunately we can't also tell PCI and PCI-X apart based on the information provided in the OFW device tree. - Add quirk handling for the ALi M5249 found in Fire-based machines which are used as a PCIe-PCIe bridge there. These are obviously subtractive decoding as as they have a PCI-ISA bridge on their secondary side (and likewise don't include the ISA I/O range in their bridge decode) but don't indicate this via the class code. Given that this quirk isn't likely to apply to all ALi M5249 and I have no datasheet for these chips so I could implement a check using the chip specific bits enabling subtractive decoding this quirk handling is added to the MD code rather than the MI one. |
