Depends what  you mean by "platform".

Basically, most of the older MCG boards will use pplus_common.c (supports
falcon/raven and hawk); most of the newer ones will use the harrier.  It
depends on whether the MCG boards are supported by one or two "board ports"
or if each board has its own "board port".  Lately, we've been separating
them out because there have been more significant differences between the
various boards and having things like residual data are not assured anymore
(or residual data that's close to correct).

Any comments Matt?

Sounds like the right place to me too.
