From 8bad4905f4da98a224ab4fd5681822d172879a59 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 5 Nov 2011 11:35:32 +0000 Subject: [PATCH] ARM: restart: ixp23xx: use new restart hook Hook these platforms restart code into the new restart hook rather than using arch_reset(). In doing so, we split out the ixdp2351 restart code into its own platform file.
