What's going on here? This file is used by all three boards. If you
need to distinguish one board's CPLD from another's, you'll have to do it
somewhere else. If the CPLDs are exactly the same and no distinction
needs to be made, then you don't need three compatible strings. Even
then, you may wish to specify the exact board as the first compatible
string, but again you'll need to patch that in elsewhere so that it
actually matches the board.
