-Subject: [PATCH] Add support for I2SE Duckbill boards
+Date: Fri, 21 Apr 2017 11:08:19 +0200
+Subject: [PATCH] arm: mxs: add support for I2SE's Duckbill boards
+
+The Duckbill devices are small, pen-drive sized boards based on
+NXP's i.MX28 SoC. While the initial variants (Duckbill series) were
+equipped with a micro SD card slot only, the latest generation
+(Duckbill 2 series) have an additional internal eMMC onboard.
+
+Both device generations consists of four "family members":
+
+- Duckbill/Duckbill 2: generic board, intended to be used as
+ baseboard for custom designs and/or as development board
+
+- Duckbill EnOcean/Duckbill 2 EnOcean: come with an EnOcean
+ daugther board equipped with the popular TCM310 module
+
+- Duckbill 485/Duckbill 2 485: as the name implies, these
+ devices are intended to be used as Ethernet - RS485 converters
+
+- Duckbill SPI/Duckbill 2 SPI: not sold separately, but used
+ in I2SE's development kits for Green PHY HomePlug Powerline
+ communication
