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
