From fbb82b03653cdb7fd1863b911e7540011259d2ce Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 20 Jan 2010 16:42:52 +0900 Subject: sh: machine_ops based reboot support. This provides a machine_ops-based reboot interface loosely cloned from x86, and converts the native sh32 and sh64 cases over to it. Necessary both for tying in SMP support and also enabling platforms like SDK7786 to add support for their microcontroller-based power managers.
