From 5cb9ddad3e8d487945c4a1e4b82575369b08be52 Mon Sep 17 00:00:00 2001 From: Lee Leahy Date: Fri, 1 May 2015 10:34:54 -0700 Subject: mainboard/intel: Add Braswell based Strago board Add the initial files to support the Intel RVP for Braswell. Matches chromium tree at 927026db This board uses the Braswell FSP 1.1 image and does not build without the FspUpdVpd.h file.
