> make CROSS_COMPILE_ta_arm32=arm-none-eabi- PLATFORM=rockchip-rk322x
Get tee.bin in this step, copy it to U-Boot root dir:
> cp out/arm-plat-rockchip/core/tee-pager.bin ../u-boot/tee.bin
Compile the U-Boot
(For Android Things Project, use Android build system.)
==================
> cd ../u-boot
> export CROSS_COMPILE=arm-linux-gnueabihf-
> export ARCH=arm
> make gva-rk3229_defconfig
> make u-boot-dtb.bin
Get u-boot-dtb.bin in this step.

> cd ../rkdeveloptool
> sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf
> autoreconf -i
> ./configure
> make
Get rkdeveloptool in you Host in this step.
Both origin binaries and Tool are ready now, choose either option 1 or
option 2 to deploy U-Boot.
Package the image
(For Android Things Project, use Android build system.)
=================
> cd ../u-boot
> rkbin/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img 0x61000000
Get uboot.img in this step.
Flash the image to eMMC
(For Android Things Project that supports AB update,
please follow google's documents.)
=======================
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
> cd ..
> rkdeveloptool db rkbin/rk32/rk322x_loader_v1.04.232.bin
> rkdeveloptool wl 0x4000 uboot.img
> rkdeveloptool wl 0x6000 trust.img
> rkdeveloptool rd
You should be able to get U-Boot log message with OP-TEE boot info.
