That's true, defconfigs are only reference configurations, but still,
I would opt for a separate defconfigs as it is more clear which target
given defconfig is meant for and it is more convenient for development
and customer to have it separate. And IMHO it's actually easier to
maintain, as you don't need to consider all three boards each time you
update defconfig and don't need to test each defconfig change on three
(right now) boards, etc.
