From bb863e85a74f0222f4486ddb1945ed9eb431d6c9 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 8 Jun 2010 09:55:40 +0000 Subject: powerpc/85xx: Fix SWIOTLB initalization for MPC85xxMDS boards The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the mpc85xx_mds_setup_arch() return early if no QE nodes present, and so SWIOTLB is never initialized. This patch fixes the issue by moving SWIOTLB code above QE.
