    sdhci: scatter-gather (ADMA) support · 2134a922
    Pierre Ossman 提交于
    Add support for the scatter-gather DMA mode present on newer controllers.
    As the mode requires 32-bit alignment, non-aligned chunks are handled by
    using a bounce buffer.
    
    Also add some new quirks to handle controllers that have bugs in the
    ADMA engine.
