[PATCH 2/3 v3] x86: ce4100: force reboot method to be KBD

From: Florian Fainelli
Date: Mon Oct 29 2012 - 09:41:52 EST


From: Maxime Bizon <mbizon@xxxxxxxxxx>

The default reboot is via ACPI for this platform, and the CEFDK bootloader
actually supports this, but will issue a system power off instead of a real
reboot. Setting the reboot method to be KBD instead of ACPI ensures proper
system reboot.
