Ok, thanks for the clarification, I misremembered the outcome
of the discussion. I've updated the reference in the mach/io.h
to no longer refer to that, but I still think it's safe to break
readw/writew on BAST ISA devices.

If we finish the multiplatform conversion for all ARMv5, I care
less about dropping s3c24xx entirely as an intermediate step,
but I definitely still like to see any board files and SoCs dropped
that have no users and are just a maintenance burden.

Ok, thanks!
