From 66038c87dab0c46d3991fbf3945d0a502d3e9905 Mon Sep 17 00:00:00 2001 From: Mario Scheithauer Date: Tue, 25 Sep 2018 17:26:32 +0200 Subject: siemens/mc_apl1: Add new mainboard variant mc_apl2 This mainboard is based on mc_apl1. In a first step, it contains a copy of mc_apl1 directory with minimum changes. Special adaptations for mc_apl2 mainboard will follow in separate commits.
