the following patch was just integrated into master: commit 01fddb11d492d00dfc8b1f42e6969838ad6db04d Author: Duncan Laurie dlaurie@chromium.org Date: Mon Feb 10 11:34:27 2014 -0800
lynxpoint: Finalize chipset before playload if not CONFIG_CHROMEOS
The Chrome OS environment sends an SMI to finalize the chipset/board at the end of the "depthcharge" payload, but there is no facility to send this command if not using the full ChromeOS firmware stack.
This commit adds a callback before booting the payload that will issue this SMI which will lock down the chipset and route USB devices to the XHCI controller.
