This is traditionally where we put the ARM SoC drivers, but
Mac has traditionally used drivers/macintosh for their custom
board etc stuff. Or is that just for any off-chip stuff?

I suppose it doesn't matter much (unless there is code under
drivers/macintosh we want to reuse for M1), but it could be a bit
confusing?

Hmm, it seems that tree is mostly about the PowerPC era Macs; the only thing enabled for x86 there is MAC_EMUMOUSEBTN. There is also platform/x86/apple-gmux.c for an x86 Mac specific thing...

We already broke tradition with the "apple," DT compatible prefix (used to be AAPL for the PowerPC Macs), and these chips aren't even just used in Macs (e.g. the iPad, which in theory people would be able to run Linux on if someone figures out a jailbreak), so perhaps it's time for another break here?
