This patch added mmc_power_off after mmc_attach_sd() i found that didn't detect the second card insert.(using SDHCI) you can see the below log.
i want to know that somebody know this issue... ->first card inserted (correct card detect) # mmc1: new SDHC card at address e624 mmcblk1: mmc1:e624 SU04G 3.69 GiB mmcblk1: p1 # # mmc1: card e624 removed -> second card inserted mmc1: error -110 whilst initialising SD card mmc1: Card removed during transfer! mmc1: Resetting controller. -> third card inserted mmc1: new SDHC card at address e624 mmcblk1: mmc1:e624 SU04G 3.69 GiB mmcblk1: p1 I added mmc_power_off() after only mmc_attach_sd().
