Do what you were going to do anyway. Wanted to open-licence the patents? Do it. But unless you can open all the firmware, no-one who knows what they're doing will want to know, in this scenario. No excuses. (As for the Raspberry Pi - actually, the stock firmware uses the ThreadX RTOS which Broadcom don't own and can't completely open-source - but they've got someone writing a set of open firmware, although it'll be a while in coming.)
