I've seen that once, for one of the ESP drivers that were supported on
both m68k and ppc (APUS, PPC upgrade to Amiga computers). But that
driver was removed long ago (after 2.6?).
In that case, the assembly file did reside in drivers/scsi/. That still
appears to be current practice (see drivers/scsi/arm/acornscsi-io.S).
Cheers,
Michael
