Just for everyone's edification... You're unlikely to see an open-source firmware for the 3G/4G cellular radio, the WiFi, or the low level Bluetooth stack (up to the HCI layer). Ever. The reason? This stuff costs a lot to develop, and the major chip vendors don't want to give any help to their competition. As for graphics... I had heard an announcement by one SoC vendor who was just putting in more general-purpose processor cores, and they had planned to do all the video decoding (such as for H.264) and OpenGL graphics in software (using Mesa?). This was allegedly going to be possible with a power budget not too much larger than the typical hardware implementations of these blocks. What ever happened to them?
