Hi, I never tried that, but basically I see two ways:

A) Check your bootargs in u-boot (printenv bootargs) and set 
root=/dev/mmblockdevicewithpartitionnumber

B) Generate an initramfs which tries to mount root from 
root=/dev/mmblockdevicewithpartitionnumber (sd card drivers are loaded 
by initramfs image, as you can see in your factory default log)
