Subject: [PATCH] arm: mxs: add support for I2SE's Duckbill boards
The Duckbill devices are small, pen-drive sized boards based on
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":
+Both device generations consist of four "family members":
- Duckbill/Duckbill 2: generic board, intended to be used as
baseboard for custom designs and/or as development board
