+Subject: [PATCH] ath79: port cybertan_part from ar71xx
+
+This patch ports the cybertan_part code from ar71xx and converts the
+driver to a DT-supported mtd parser. As a result, it will no longer
+add the u-boot, nvram and art partitions, which were never part of
+the special Cybertan header.
+
+Instead these partitions have to be specified in the DT, which has the
+upside of making it possible to add properties (i.e.: read-only), labels
+and references to these important partitions.
+
