[PATCH V3] ARM: Kirkwood: new board USI Topkick

Jason Cooper jason at lakedaemon.net
Sun Oct 21 22:15:35 EDT 2012


This is a new kirkwood box made by Universal Scientific Industrial, Inc.
The product description is here:

http://www.usish.com/english/products_topkick1281p2.php

It is very similar to the dreamplug and other plug devices, with the
exception that it has room for a 2.5" SATA HDD internally.

 - corrected comments missed during copy/paste
 - sorted topkick dtb Makefile entry alphabetically

Changes since V1:
 - changes nr-ports to 1 for sata0
 - included board in defconfig
 - trimmed #includes
 - added mvsdio init call
