Here is the step-by-step to boot U-Boot on phytium durian board.

Compile U-Boot
==============
  > make durian_defconfig
  > make

Get the prebuild binary about BPF
=================================
  > cd ../
  > git clone https://github.com/phytium-durian/bpf.git

Package the image
=================
  > cd bpf
  > cp ../u-boot/u-boot.bin ./
  > ./dopack

  The fip-all.bin is the final image.

Flash the image into the spi nor-flash
======================================
  Any spi nor-flash and appropriate tool can be used to flash.
  For example, we choose the S25FL256 chip that produced from
  SPANSION company and EZP_XPro V1.2.

Reset the board, you can get U-Boot log message from boot console:

Power on...
Start pcie setup!
End pcie setup!
Start ddr setup!
End ddr setup!
