From cf05528238c2ef91ad81658158616b3a75b74642 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20Bie=C3=9Fmann?= Date: Mon, 18 Jul 2011 09:41:03 +0000 Subject: ARM: remove obsolete at91rm9200 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The big "ARM: remove broken boards" series deletes all boards using obsolete arm920t/at91rm9200 arch code. Therefore we can safely remove this code now.
