Have you actually tested eMMC support? It seems to be broken when the
system boots off SD card, "mmc info" returns "unable to select a mode
: -70". I have a strong suspicion that it's due to rk_i2c being broken
for rk3568, with debug enabled it complains "I2C Send Start Bit
Timeout" on every i2c transaction.
Could you please share "mmc info" and "regulator status -a" output
from your build?
Regards,
Vasily
