Yes, I2C is generally working and should make a difference in Linux kernel
booting.
It seems that your bootwrapper is somehow not copying the correct MAC address
to the device-tree. Not sure what's going wrong here. We usually don't use
the bootwrapper but boot the uImage directly from U-Boot on all 4xx systems.
You might want to debug the bootwrapper code, if possible drop the bootwrapper
and use the uImage with a newer, device-tree enabled U-Boot version.
Best regards,
Stefan
