+Using fastboot on rk3288
+========================
+- Define GPT partition layout like kylin_rk3036(see include/configs/kylin_rk3036.h)
+- Write GPT partition layout to mmc device which fastboot want to use it to
+store the image

+        => gpt write mmc 1 $partitions
+
+- Invoke fastboot command to prepare
+
+        => fastboot 1
+
+- Start fastboot request on PC
+
+        fastboot -i 0x2207 flash loader evb-rk3288/spl/u-boot-spl-dtb.bin
