Hi Andrei,

Since SDHCI_DMA_ADDRESS and SDHCI_ARGUMENT2 in actually the same register, probably ...

#define SDHCI_ARGUMENT2		SDHCI_DMA_ADDRESS

is a good idea?

How about changing these names explicitly to _AUTO_CMD12 and _AUTO_CMD23? That way we are less likely to get confused with App commands with same names.

Same comment as above.
