Yes, that is what I'd be inclined to so.  In fact, if faced with
designing an ABI for your NXP SDMA processor from scratch I'd avoid
the octets_per_byte conversion entirely by using octets from assembly
onwards.  Addresses would always be multiples of two, and you'd design
relocations to suit.  Users of course would need to write ". + 2"
rather than ". + 1" and similarly in other expressions involving
addresses.
