From 6d85e2b0b6bed6ae7070426d5e43174c593e075c Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 17 Nov 2011 14:36:23 +0100 Subject: ARM: new platform for Energy Micro's EFM32 Cortex-M3 SoCs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are still some missing parts (e.g. board support, device trees), but with these bits added on top of this patch I can successfully boot a EFM32GG-DK3750 board that uses an EFM32GG990F1024.
