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
==================
> cd ../u-boot
> export CROSS_COMPILE=arm-linux-gnueabihf-
> export ARCH=arm
> make evb-rk3229_defconfig
> make
> make u-boot.itb
Get tpl/u-boot-tpl.bin, spl/u-boot-spl.bin and u-boot.itb in this step.
Compile the rkdeveloptool

option 2 to deploy U-Boot.
Package the image
=================
> cd ../u-boot
> tools/mkimage -n rk322x -T rksd -d tpl/u-boot-spl.bin idbloader.img
> cat spl/u-boot-spl.bin >> idbloader.img
Get idbloader.img in this step.
Flash the image to eMMC
=======================
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 64 u-boot/idbloader.img
> rkdeveloptool wl 0x4000 u-boot/u-boot.itb
> rkdeveloptool rd
Flash the image to SD card
==========================
> dd if=u-boot/idbloader.img of=/dev/sdb seek=64
> dd if=u-boot/u-boot.itb of=/dev/sdb seek=16384
You should be able to get U-Boot log message with OP-TEE boot info.
