The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

This is meant as a quick might-need-to-know page for Allwinner A10 (and potentially A13 and later) SoCs
