You mean something like http://linux-sunxi.org/Linux_mainlining_effort ?

You should really do a bit of research before starting a thread like
this one. This webpage has been around for like 9 monthes now on the wiki 
of a community you pretend to represent (even though I fail to get how
you can pretend such thing, but that's another topic).

3.8, as shown in the wiki page

Again, wiki.

A10, A13 for the moment. I just received hardware with A10s, A20 and A31
that I need to work on, but support should come quite soon. I already
have some patches pending to be tested on an A31 board, but didn't have
as much time as I wanted lately to actually set a proper environment to
test them.
