From 411f0f3edc141a582190d3605cadd1d993abb6df Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Sun, 6 May 2007 14:49:09 -0700 Subject: Introduce CONFIG_HAS_DMA Architectures that don't support DMA can say so by adding a config NO_DMA to their Kconfig file. This will prevent compilation of some dma specific driver code. Also dma-mapping-broken.h isn't needed anymore on at least s390. This avoids compilation and linking of otherwise dead/broken code. Other architectures that include dma-mapping-broken.h are arm26, h8300, m68k, m68knommu and v850. If these could be converted as well we could get rid of the header file.
