From 7ac18a3845145f4f48e611640e33918ae450f955 Mon Sep 17 00:00:00 2001 From: "Arnaud Patard (Rtp)" Date: Thu, 17 Feb 2011 15:31:28 +0100 Subject: Introduce EFIKA_COMMON The Genesi EFIKA MX and EFIKA Smartbook are sharing a lot of things so it makes sense to create a common file for both devices and a specific file for each. No functionnal change except dropping uart 1 & 2.
