the A10 is the only sun4i we know of, the A31 is the only sun6i we know 
of, and the A20 is the only sun7i we know of... they'll soon run out of 
numbers... :|

Also, to avoid confusions with their poorly chosen marketing name, you 
could use the internal chip name aw1623 for the A10 and aw1626 for the 
A13 instead. This value can be read from the BROM and it's commonly used 
in allwinner sources.
