The solution to "We have some people who speak French and other people who
speak German" is not to invent Esperanto ;-)

Using one or the other internally is fine (we don't care what you do),
but we want to see memcpy().  By the way, the documentation I found for
ScsiPortMoveMemory() seems to indicate that it's memmove(), not memcpy().
Mapping memcpy() to ScsiPortMoveMemory() is fine ... but you can't
realiably go the other way.
