A10, A13, A20 have full open source system code for a long long time, and these days even integrated in mainline u-boot & kernel, including initialization from bare metal. Full DRAM setup etc. And now DRAM setup code and more for the whole range of SoCs have suddently been released as open source by Allwinner which removes a large part of the burden of getting the other SoCs supported at system level. The SoC user guides have also improved by far compared to the early A10 user guides we got access to years ago, plus are now officially published and not just randomly leaked. If you look at the openness then VPU and GPU is the most sore parts in the Allwinner SoCs at the moment. Not so much because they depend on everything else but because everything about them is closed down tightly by Allwinner. There is also some issues in display interfacing where there is relations to third party interest organisations and content protection. Please ignore what is in the Allwinner SDK releases and focus on what is available in open versions or documented. The silly fact that some later SDK releases have closed down some things which was open before do not make the already openly published versions closed, or that support for those have been dropped by linux-sunxi community kernel.
