Dear Przemyslaw Marczak,

It is possible to boot device using a micro SD or eMMC slots.
In this situation, boot device should be registered as a block
device 0 in the MMC framework, because CONFIG_SYS_MMC_ENV_DEV
is usually set to "0" in the most config cases.

It looks little confused.
Could you please re-arrange this code like this?
If re-arrange the below code, i want to call the dwmmc-init function at first.
Is there a special reason for sequence(sdhci->dwmmc)?
Best Regards,
Jaehoon Chung
Please look at my proposed solution in the reply to Minkyu email.
Thanks,
