From d301425fbfc7a0c13df2a2965a289c829e2b1ba3 Mon Sep 17 00:00:00 2001 From: Hannes Petermaier Date: Tue, 3 Feb 2015 13:22:27 +0100 Subject: [PATCH] board/BuR/common: try to setup cpsw mac-address from the devicetree since we have a dtb blob programmed on the board we try to setup the cpsw interface with the programmed mac. If this method fails, we fall back to the device-fuses.
