This patch adds sdma_boundary member to struct sdhci_host to give more flexibility to drivers to control the sdma boundary buffer value and also to fix issue on some sdhci controllers which are broken when HOST SDMA Buffer Boundary is programmed in Block Size Register (0x04) when using ADMA. Qualcomm sdhci controller is one of such type, writing to this bits is un-supported. Default value of sdma_boundary is set to SDHCI_DEFAULT_BOUNDARY_ARG.

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.
