From 7dd19e755dbe481ae42590dbd921dfd47e94779c Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 4 Feb 2008 17:39:00 +0100 Subject: [ARM] 4818/1: RealView: Add core-tile detection This patch adds the core-tile detection and only enables devices if the corresponding tile is present. It currently detects the ARM11MPCore via the core_tile_eb11mp() macro.
