[U-Boot] spl export fdt crashes

[matti kaasinen]

Hi!
I tried to useing falcom mode from nand flash:
ti-u-boot,
am335x based board using modified am335x_evm.
include/configs/am335x_evm.h falcon mode variables untouched.

I ran manually commands presented in:
https://git.ti.com/ti-u-boot/ti-u-boot/blobs/ti-u-boot-2016.05/board/ti/am335x/README
with the exception that I took dtb spl-os partition, so nand read instead
of load nand, usin nand read. I get following printout from falcon mode
preparation:
=> run nandargs
=> nand read ${loadaddr} NAND.kernel

NAND read: device 0 offset 0x200000, size 0x800000
 8388608 bytes read: OK
=> nand read ${fdtaddr} NAND.u-boot-spl-os

NAND read: device 0 offset 0x80000, size 0x40000
 262144 bytes read: OK
=> run nandargs
=> spl export fdt ${loadaddr} - ${fdtaddr}
