Amusingly, Apple actually use 'apple,firestorm' and 'apple,icestorm' for the CPUs in their devicetrees for these machines, so those will end up identical :) (they don't use apple-related prefixes for any other compatible strings at all, it's a mess). But we don't care about what their ADTs (Apple DTs) do in Linux anyway, the bootloader abstracts all that out and we'll be dealing with mantaining proper DTs ourselves. >> Makes sense.

Thanks for pointing this out; this was actually unintentional. I based it off of an old dts I'd written ages ago and forgot to revisit the license. I even have it marked GPL-2.0+ in the copy in our bootloader repo, which is otherwise supposed to be MIT for original code... -- Hector Martin (marcan@marcan.st) Public Key: https://mrcn.st/pub
