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.
