Documenting about the status about this device

Currently, I've managed to fix various problems either by copying a patch from a different device or disabling configurations one by one, however the kernel failed to compile because of undefined references to various things. I could paste the logs here, but I don't know if it's appropriate.

Resolved compiling issues

ANDROID_MAJOR_VERSION

Solved with a patch from another Samsung device.

Issues

Vendor kernel

It might not be made.. I don't even know what vendor files are important!
