From 212c7fd614377fef4415d94856a59e9f484aa439 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 2 May 2017 09:58:00 +0200 Subject: [PATCH] stmmac: Add support for SIMATIC IOT2000 platform The IOT2000 is industrial controller platform, derived from the Intel Galileo Gen2 board. The variant IOT2020 comes with one LAN port, the IOT2040 has two of them. They can be told apart based on the board asset tag in the DMI table. Based on patch by Sascha Weisenberger.
