there are several parts of Android, which are not part of the mainline
kernel. Others are in staging. See
http://elinux.org/Android_Mainlining_Project for more details.

Regarding drivers for chips on your board, see the kernel
documentation about coding style
(http://lxr.free-electrons.com/source/Documentation/CodingStyle) and
submitting drivers
(http://lxr.free-electrons.com/source/Documentation/SubmittingDrivers),
submitting patches etc.

Beware to send the patches/drivers to the right mailing list (see the
MAINTAINERS file).

If you want to add the board itself and it is ARM based, then you have
to create a device tree file. I think the older board files are no
more accepted in the mainline kernel.

Hope that answered your question.
Cheers and happy hacking.
Matthias
