Can't the ata/ATA thing be fixed by simply fixing device trees where it
happens? strncmp seems the standards-compliant route to take.. why clutter
the common parsing routines with fixes for deviant platforms?

The Mac obviously has a few of_platform things where you can add a
compatible search for ata then ATA, keeping it all in the drivers (where
relevant) and in the platform setup (where necessary)
