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.
