   4 Subject: [PATCH 05/18] mtd: physmap_of: Move custom initialization
   5
   6 In order to be able to assign custom complex mappings
   7 to the physmap_of plugin for Gemini, move the initialization
   8 so that the simple map is initialized before we enter the
   9 platform-specific functions so the latter can override
  10 them.
