Because I understood that it's not sdhci specific cookies. It can be used generally, doesn't? Role of post/pre_req() in host controller is the doing dma_map/unmap(). And data's cookies only needs to notice whether dma is mapped or unmapped, etc. Well, If it's really private value and should be added other cookies values in future, i will put cookies in dw_mmc.h. (it should be duplicated in sdhci and dwmmc.)
