> #define  SDHCI_CMD_RESP_MASK    0x03
> #define  SDHCI_CMD_CRC          0x08
> #define  SDHCI_CMD_INDEX        0x10
> #define  SDHCI_CMD_DATA         0x20

My idea was that it belongs more to the command definitions, thus sd.h.
But as long as there is nothing to be solved at core-level sdhci.h might
do for now as well.
