   2 Subject: [PATCH] ath79: port cybertan_part from ar71xx
   3
   4 This patch ports the cybertan_part code from ar71xx and converts the
   5 driver to a DT-supported mtd parser. As a result, it will no longer
   6 add the u-boot, nvram and art partitions, which were never part of
   7 the special Cybertan header.
   8
   9 Instead these partitions have to be specified in the DT, which has the
  10 upside of making it possible to add properties (i.e.: read-only), labels
  11 and references to these important partitions.
