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
