+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!
