Just "useful" (as in generally useful, but mostly dead code here),
or actually used somewhere?

Best regards,

Wolfgang Denk

They are used in other patches in this series. The only exception is the
#defines for gfx burst size, which were used in V1, but not in this
version. I kept the gfx burst size defines in the hope they will be
useful to someone, but I can remove them if you think this shouldn't be
done.
