From bdec0ea2cf82b2b763818e9f8e95e70d45899dfe Mon Sep 17 00:00:00 2001 From: Mario Scheithauer Date: Mon, 27 Feb 2023 12:44:26 +0100 Subject: [PATCH] mb/siemens/mc_ehl5: Add new board variant based on mc_ehl2 This mainboard is based on mc_ehl2. In a first step, it contains a copy of mc_ehl2 directory with minimum changes. Special adaptations for mc_ehl5 mainboard will follow in separate commits.
