[U-Boot] [PATCH v4 2/4] mmc: Implement card detection.

[Jason Liu]

2012/1/2 Thierry Reding <thierry.reding at avionic-design.de>:
> Check for card detect each time an MMC/SD device is initialized. If card
> detection is not implemented, this code behaves as before and continues
> assuming a card is present. If no card is detected, has_init is reset
> for the MMC/SD device (to force initialization next time) and an error
> is returned.
