    Yeah, in theory the code is "somewhere", but in practise the guys at broadcom have to configure their source tree to make a "start.elf" that runs on the 'pi. And there might be code to write to make the "can take a picture" code talk to Linux, not just the linux code to take advantage of it, but also the code on the GPU that talks to Linux.

     

    On the other hand, even if there is a Nokia phone with broadcom support, maybe nokia said: "We've heard that Nikon makes good video processing software".... -- "but that'll add $3 to the price of the SOC!"... -- "It's important to us to have the best video processing available, NOW, so we'll pay for it".

    I read on the Pi website that they were writing the Linux side code to communicate with the camera driver, although was already available using something called OpenMAX.

     

    From what I've read around, the broadcomm GPU does all the camera work in the Nokia smartphones, even the 808.
