Hi Chris..

My question is others..I agreed the using frequency table..

But my questions is this...
For example, if f_min is 300KHz, you can the below message.

mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz
mmc1: mmc_rescan_try_freq: trying to init card at 300000 Hz
mmc1: mmc_rescan_try_freq: trying to init card at 300000 Hz

In other words, first init card with 400KHZ, 
but second/third to init with 300KHz. 
i think not necessary that try to initialize the two times with 300KHz.

I want to know your opinion..

Regards,
Jaehoon Chung
