+Here is the step-by-step to boot U-Boot on rv1108 evb.
+
+Get ddr init binary
+==============================================================================
+  > git clone  https://github.com/rockchip-linux/rkbin.git
+  > dd if=./rkbin/rv1x/rv1108ddr.bin of=ddr.bin bs=4 skip=1
+
+Compile  U-Boot
+===========================
+  > make CROSS_COMPILE=arm-linux-gnueabi- evb-rv1108_defconfig  all
+  > ./tools/mkimage  -n rv1108 -T rksd -d ddr.bin spl.bin
+  > cat spl.bin u-boot.bin > u-boot.img
+
+Flash the image by rkdeveloptool
+================================
+rkdeveloptool can get from https://github.com/rockchip-linux/rkdeveloptool.git
+
+Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
+  > rkdeveloptool db ./rkbin/rv1x/RV1108_usb_boot.bin
+  > rkdeveloptool wl 0x40 u-boot.img
+  > rkdeveloptool RD
+
+You should be able to get U-Boot log message from boot console:
