    While mandating FDT is a massive advance over arm32, if there's a chance
    that ACPI-based AArch64 platforms will ship in a similar timeframe to
    FDT then I think we should ensure that ACPI and FDT are merged
    beforehand - the alternative is that people are going to end up writing
    the same hardware driver twice for different firmware implementations. I
    don't think anyone benefits from introducing a platform that has
    multiple device representations[1]

    [1] Yeah x86 has the same problem with PNP and ACPI and PCI and given
    how much pain that's caused me I wish someone had complained at the time
