You will want to target the Rockchip RK3188 and Allwinner A20. The
reason is that we can design hardware around these SoCs such that the
hardware can be booted without any proprietary pieces. Proprietary
software is a huge security threat. We are all currently dependent on it
because our hardware is dependent on it.

It's fairly well known within the free software community by those
working on hardware related projects that there are almost certainly
backdoors in Intel and AMD hardware (American companies). It's
advertised as a remote management functionality. In reality it can't be
disabled, manufacturers can't design around it, they won't give us the
source code, and it posses a serious security threat. They are hiding a
backdoor in plain sight on behalf the of the US government (most likely
scenario anyway).

Fortunately we know where China's been hiding its backdoors and it's at
the OS/bootloader level. At least that is the case with the systems
based around the Allwinner A20. Fortunately we can get the complete set
of corresponding sources for the critical functionality of this SoC.
Between the two pieces of information we can be reasonably confident
that combining this SoC with a set of other components where we have the
complete set of corresponding sources secure devices can be developed.

I've been involved in various projects to get sources released for
components where we have had no options. For example there were no
802.11n USB wifi chips post draft-n so I started working on getting the
complete set of sources out of one of the major companies designing USB
wifi chips.

We have a Crowd Funding campaign going on right now intended to make it
easier to design secure devices. The schematics are available for a
laptop and desktop design and these devices are based around a new
'Computer Card' standard called EOMA68. You can even download the
sources for the keyboard/screen/touchpad controller. With these designs
available and the new standard it should be relatively easy to design
other devices or upgrade to a newer Computer Card without replacing the
entire device. So for example when a computer card comes out with the
quad core Rockchip RK3188 any devices designed around this standard can
be easily upgraded.

There are a few devices I'd suggest focusing Tails development around as
they have the same SoCs which are or will be used in the above projects
(because of the source code situation). Doing so will enable users to
eventually improve there defensive posture.

For the ARM RockChip RK3188 here is probably a good development board to
use:

The original Banana Pi and the original Cubie Board contain the
Allwinner A20 and are good development choices:
