Refactor DMA support to allow it to be provided by a set of call-backs that are provided by a host driver. The motivation is to allow multiple DMA implementations to be provided and instantiated at run-time. Instantiate the existing DMA implementation from the sh_mobile_sdhi driver which appears to match the current use-case. This has the side effect of moving the DMA code from the tmio_core to the sh_mobile_sdhi driver. A follow-up patch will change the source file for the SDHI DMA implementation accordingly. Another follow-up patch will re-organise the SDHI driver removing the need for tmio_mmc_get_dma_ops().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
