2012/1/2 Thierry Reding thierry.reding@avionic-design.de:
The new API no longer uses the extra cd parameter that was used to store the card presence state. Instead, this information is returned via the function's return value. board_mmc_getcd() returns -1 to indicate that no card-detection mechanism is implemented; 0 indicates that no card is present and 1 is returned if it was detected that a card is present.
The rationale for this change can be found in the following email thread:

In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter. Furthermore the cd parameter was used to mean "card absence" in some implementations and "card presence" in others.
