This is all I need for now to get Android booting with a mainline kernel, no fancy features though that make the device worthy of being a phone (pending hardware drivers). Perhaps replacing these config fragments with gki_defconfig upstream is a good idea - as discussed with John - but that's not something for me to decide nor embark on :). Having them upstreamed might be nicer than finding the appropriate corresponding downstream tree.
