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 consists 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
