From 4692d77fc3c8978a36406a3cf9e8b899f86f68f1 Mon Sep 17 00:00:00 2001 From: Alessandro Rubini Date: Wed, 4 Apr 2012 19:39:58 +0200 Subject: x86-32: Introduce CONFIG_X86_DEV_DMA_OPS 32-bit x86 systems may need their own DMA operations, so add a new config option, which is turned on for 64-bit systems. This patch has no functional effect but it paves the way for supporting the STA2x11 I/O Hub and possibly other chips.
