LG Optimus Black (P970) codename sniper support

The LG Optimus Black (P970) codename sniper is a smartphone that was designed
and manufactured by LG Electronics (LGE) and released back in 2011.

It is using an OMAP3630 SoC GP version, which allows running U-Boot and the
U-Boot SPL from the ground up. This port is aimed at running an Android version
such as Replicant, the fully free Android distribution. However, support for
upstream Linux with device-tree and common GNU/Linux distros boot commands
could be added in the future.

For more information about the journey to freeing this device, please read the
series of blog posts at:
