What exactly are you tried to change on a per-board basis ? Assuming
it is variables, you can use the standard OVERRIDES mechanism to
have a version specific bbappend, that changes variables on a per
board basis.

i.e.

      FOO_<machine name> = "bar"
      FOO_<another machine name> = "bar2"

Assuming the generic recipe uses these variables appropriately, you'll
be fine.
