commit 56ebe779e9c770995268a8cf739ffa2d509014ad Author: David Hendricks dhendrix@chromium.org Date: Tue Feb 5 15:24:54 2013 -0800
snow: remove dead code from bootblock
This attempts to clean out some dead code which was copy + pasted into Snow's bootblock.c file, along with some unnecessary headers.
Since the max77686 driver and vtxprintf are not built when bootblock-y is set, those will remain for now.
