I worked at a startup producing an Android device funded by Intel and Intel wouldn't even give us source code to all the parts of the OS. We had to deal with binary blobs copied into the Android source tree for things like the HAL (hardware abstraction layer) and fastboot. They were things we really needed to customize too because their fastboot referenced buttons our device didn't have and things like that. It was pretty ridiculous. Previous to that I worked on a TI OMAP solution and the source for that was much more open. We had a to extract a custom SGX package for the graphics processing, but otherwise it was much closer to the Android Open Source Project. At least we could customize their x-loader and u-boot as needed. Too bad TI OMAP died.
