   4 Subject: [PATCH] arm: mxs: add support for I2SE's Duckbill boards
   5
   6 The Duckbill devices are small, pen-drive sized boards based on
   7 NXP's i.MX28 SoC. While the initial variants (Duckbill series) were
   8 equipped with a micro SD card slot only, the latest generation
   9 (Duckbill 2 series) have an additional internal eMMC onboard.
  10
  11 Both device generations consist of four "family members":
  12
  13 - Duckbill/Duckbill 2: generic board, intended to be used as
  14   baseboard for custom designs and/or as development board
  15
  16 - Duckbill EnOcean/Duckbill 2 EnOcean: come with an EnOcean
  17   daugther board equipped with the popular TCM310 module
  18
  19 - Duckbill 485/Duckbill 2 485: as the name implies, these
  20   devices are intended to be used as Ethernet - RS485 converters
  21
  22 - Duckbill SPI/Duckbill 2 SPI: not sold separately, but used
  23   in I2SE's development kits for Green PHY HomePlug Powerline
  24   communication
