commit 0e0a682737577fa06bd9f45c02aef26d59cba1ef
Author: Nicky Sielicki <nlsielicki at wisc.edu>
Date: Mon Jun 8 18:58:50 2015 -0500
[NOTFORMERGE] attempts to upstream swanky.
Most of this verbatim from firmware-swanky-5216.238.B, some of it
modified as to try to match differences between rambi in 5216.238.B
and rambi in upstream.
