Actually that would be
board/[<vendor>/]<board>/

OK.

1. and 2. are actually the same (2. being the special case of N=1)

I don't get this. Why don't we just pass the required make target
from the top level Makefile? If we want to build "onenand-ipl-2k.bin"
then this would result in running "make onenand-ipl-2k.bin" in the
respective directory - this is then also independent of whether this
image contains support for one specific boot device or for any set of
different devices.
