There's no exact way right now.  But it breaks down like this, if you
have a port which does _not_ need to change include/asm-ppc/serial.h,
they can all go in arch/ppc/platforms.  If you change
include/asm-ppc/serial.h AND newBoard_serial.h needs to include
newBoard.h, they both go in include/asm-ppc/platforms/.

If you're 8xx or 8260 tho, they always go in include/asm-ppc/platforms
because of how m8xx/m8260 ports work.

And there's always exceptions to the rule to boot :)
