looks like it has always been dead code on the Blackfin side having
originated from the m68k port.

we can split the changeset to m68k & blackfin, or just let the m68k
guys run the thing through their tree.  i'm ok with it either way ...
i promise not to introduce conflicts into the blackfin file in the
mean time ;).
