From b60f187fecee5d9dceb89773e15f976fe21d893a Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 26 Jun 2012 21:02:54 +1000 Subject: [PATCH] m68k: use simpler dma_alloc_coherent() for ColdFire CPUs On all ColdFire platforms (whether MMU enabled or not) we want to use the simple page based dma_alloc_coherent. We don't want the virtual mapping version that is used on classic m68k setups. So modify the conditionals to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU builds.
