platform: Enable support for Pi2+

  • It looks like a new Raspberry Pi 2+ is coming soon; maybe for industrial uses and supply chain reasons.

  • A version with SATA or USB3 would be nice. That would extend potential use cases a lot since we could use faster storage.

  • I'm guessing/hoping it's going to be very similar to https://getchip.com/pages/chip in both connectivity (WiFi/BT) and built-in storage... and hopefully price.

  • well I would hope there would be a new Pi coming out... eventually.
