Add DMA support for Microblaze. There are some part of this new feature: 1. Basic DMA support 2. Enable DMA debug option 3. Setup notifier Ad 1. dma-mapping come from powerpc and x86 version and it is based on generic dma-mapping-common.h Ad 2. DMA support debug features which is used in generic file. For more information please look at Documentation/DMA-API.txt Ad 3. notifier is very important to setup dma_ops. Without this part for example ll_temac driver failed because there are no setup dma operations. Signed-off-by: Michal Simek <monstr@monstr.eu>
