Freaking *awesome* Rob, this really really needs to happen.

It still needs lots of work and polish. I have Bluetooth (HCI) over UART on the Nomadik and Ux500, both with DMA support for the PL011 too. So I hope to be able to utilize this. (The HCI transport is then used for GPS, FM radio and whatnot but that is another issue.)
