We probably don't have time to resolve this at this point, but I would be very interested in investigating what level of common helper libraries could be possible to have. Could you remind me of this once all the platforms have been migrated to Tianocore (let's say January)? Could you separate this into two patches - one importing the driver, and one adding your modifications?
