For whatever it is worth I thought Finn's patch was the best approach
(https://lkml.org/lkml/2018/5/17/333, "m68k: Set default dma mask for
platform device").

We seem to be hitting quite a few places (within m68k) that otherwise
need individual fixes. There is no immediate need to revert existing
changes that have already been applied if we use this now either
(like my FEC fix, commit f61e64310b75 "m68k: set dma and coherent
masks for platform FEC ethernets").

Regards
Greg
