[U-Boot] uboot load ftb

[张扬]

Hi all
  I‘ve got some issues with load ftb to work with my board (mpc8313erdb)
  My serial print errors as follow:
       ERROR: /chosen node create failed
 I used the following command to generate my dtb。
dtc -f -b 0 -O dtb -I dts -R 8 -S 0x3000 -o my.dtb my.dts

                                                                 thanks
