Which error are you referring to?

What kind of flash chip do you have?  Does the node in the device tree
accurately describe it (four interleaved 8-bit chips that only do JEDEC
and not CFI)?

These MAC addresses should have been set in the device tree.  If you're
using U-Boot, it should be doing the fixup.

This is a problem with the root filesystem, not the kernel.
