From 50d2e37faf5bb2fd154d4a1eeac465f8016e1f65 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Tue, 12 Aug 2014 17:59:41 +1000 Subject: plat/palmetto: Add shutdown and reboot Rebooting and power down for the Palmetto is done by the BMC, which we speak to over the BT interface using IPMI. Implement the IPMI chassis commands which are used for power control, and hook them up to the palmetto platform callbacks for shutdown and reboot.
