From 2399ef73859f7ef54d2da9c3274c01f86726eff8 Mon Sep 17 00:00:00 2001 From: Markus Hubig Date: Tue, 7 Aug 2012 17:43:23 +0200 Subject: at91: Add support for taskit AT91SAM9G20 boards. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds support for the AT91SAM9G20 boards by taskit GmbH. Both boards, Stamp9G20 and PortuxG20, are integrated in one file. PortuxG20 is basically a SBC built around the Stamp9G20.
