From 3366e3585fbf0d40ce6f2382b544851cf4df1654 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 30 Mar 2010 12:38:01 +0900 Subject: sh: Move platform smp ops in to their own structure. This cribs the MIPS plat_smp_ops approach for wrapping up the platform ops. This will allow for mixing and matching different ops on the same platform in the future.
