I suspect the File System Protocol Interface error is related to the 
"FDT_ERR_BADMAGIC" above. The latter usually indicates that U-boot was 
not able to find the FDT at the emplacement provided.
Do you know if the firmware provide a Device-Tree? You can check with 
from the U-boot prompt with "fdt /". You should get some output with it.
If not you will need to load a Device-Tree from a storage or network.
