commit 271b5708d127cb08ca4bf4c0c9f8f065838c00e9 Author: Gabe Black gabeblack@chromium.org Date: Wed May 29 16:42:31 2013 +0200
beaglebone: Force on every other user LED to show that coreboot is running.
Until we get serial working, this is a good way to show that coreboot is running. It can be removed once we have better methods.
