Yes. This can be useful when you can imagine to add functionality into a
specific direction. But in this case there were tons of mailbox definitions
(always defined 32 times each) which we will not use in this way in the netdev

Just take a look into bfin_can.h and what is really used in bfin_can.c from
those defines and you will see.
