[U-Boot] STM32F7 SD/MMC Card Driver - Testing/Review

[Philipp Rossak]

Hi Jaehoon,

Thanks for that hint!

I uploaded two logs to pastebin.

Log [1] is a sandisk ultra 32gb sd card. This time I didn't got it work 
properly.

Log [2] is from an other 2gb sd card where I pressed the reset button 
until I received data from CMD 17 command.

Right now there are a lot of debug outputs, to make it for me easy for 
me to find the errors. The most of them will be removed later.

Best Regards,

Philipp Rossak
