I have used Raspberry Pi for my bachelor thesis. What I wondered is that GPU is used for boot process: "Is there a GPU binary? Yes. The GPU binary also contains the first stage bootloader." [1] There is this boot programm Video Core (VC). Thats the one that resides in /opt/vc . As far as I know, that tool is resonsible for boot and I can guess I would say second stage. But it is very difficult to use this tool and GPU sepcifications were not public [2]. Maybe you find other images than the offical one, that use barebox as default [3]? I have heard many stories about Raspberry Pi foundation being set up by Broadcom to make their devices popular. I do not remember the sources. No offense to the guys from raspberry pi foundation. Working with the bcm2835.c file to implement an SPI user-space modul I got a similar impression. On LinuxTag 2013 in Berlin this plattform has been criticized for not conforming to open hardware standards. (The eagle files were hard to find). If you find a solution nevertheless, I would be very much interested as well.
