Tue Oct 6 18:57:58 PDT 2015
From: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>
Add the initial device tree for the R8A7791 SoC based Porter low cost board
(which is a slightly modified version of the Henninger board).
SCIF0 serial port support is included, so that the serial console can work.
