MMC: add weak function to detect MMC/SD card 2010-03-07T18:36:36+00:00 Stefano Babic sbabic@denx.de 2010-02-05T14:04:43+00:00 11fdade294b4d60c19ae861515aabddca1278deb Most controllers can check if there is a card in the slot. However, they require pins that could be not available because required by other functions and the detection of a card must be performed in another way. This patch adds a weak function that a board can implement to add its internal custom way to check the presence of a MMC/SD card. Signed-off-by: Stefano Babic <sbabic@denx.de>
