as requested by many forum users we released all the Android sources (U-Boot, Kernel & File System). The tar.gz is quite big (2.6gb) but we managed to open both EU and US mirrors as well as a Torrent channel (Please seed).
Waiting for the 2013 (which will be available soon) we also released the U-Boot 2009 for the Linux Distributions (Ubuntu, Debian etc.).
You can find all the sources available in our Downloads section, tab Sources.
