From 09ab856c85b59a04bb14146533d19edd4ccf1467 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Fri, 16 Jan 2015 12:08:38 -0800 Subject: Danger: Initial mainboard import This adds a directory with files copied over from Brain along with build-related changes so that emerge-veyron_danger works. The next patch will account for other differences.
