I resent my series to deprecate almost all board files recently, and
that is now in linux-next. Unless Russell has any last minute objections,
I would now expect that we can remove all the deprecated files after
7.3-LTS is out, and that includes the drivers/scsi/arm/ directory.

My original plan was to do this all two years earlier, but since we are
close to another LTS kernel, I think it makes sense to wait for that
before removing any code that potentially still works.
