Currently it is able to boot a linux kernel and system
to console with the miniloader run as fist level loader.

Here is the step-by-step to boot to U-Boot on rk3368.
Get miniloader and trust.img form rockchip vendor u-boot source code
==============================================================================
> git clone https://github.com/rockchip-linux/u-boot.git rockchip-uboot
> cd rockchip-uboot
> make rk3368_defconfig /*chose px5_defconfig if you run a px5 platform here*/
> ./mkv8.sh
Compile the upstream U-Boot
===========================
> cd u-boot
> make CROSS_COMPILE=aarch64-linux-gnu- sheep-rk3368_defconfig all
Package u-boot for miniloader
================================
> ../rockchip-uboot/tools/loaderimage --pack --uboot 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 ./rockchip-uboot/rk3368_loader_v2.00.256.bin
> rkdeveloptool wl 0x6000 ./rockchip-uboot/trust.img
> rkdeveloptool wl 0x4000 ./u-boot/u-boot.img
> rkdeveloptool RD
You should be able to get U-Boot log message from boot console:
