Introduction
============

RK3399 key features we might use in U-Boot:
* CPU: ARMv8 64bit Big-Little architecture,
*      Big: dual-core Cortex-A72
*      Little: quad-core Cortex-A53
* IRAM: 200KB
* DRAM: 4GB-128MB dual-channel
* eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
* SD/MMC: support SD 3.0, MMC 4.51
* USB: USB3.0 typc-C port *2 with dwc3 controller
*      USB2.0 EHCI host port *2
* Display: RGB/HDMI/DP/MIPI/EDP

evb key features:
* regulator: pwm regulator for CPU B/L
* PMIC: rk808
* debug console: UART2

In order to support Arm Trust Firmware(ATF), we can use either SPL or
miniloader from rockchip to do:
* do DRAM init
* load and verify ATF image
* load and verify U-Boot image

Here is the step-by-step to boot to U-Boot on rk3399.

Get the Source and prebuild binary
==================================

  > mkdir ~/evb_rk3399
  > cd ~/evb_rk3399
  > git clone https://github.com/ARM-software/arm-trusted-firmware.git
  > git clone https://github.com/rockchip-linux/rkbin.git
  > git clone https://github.com/rockchip-linux/rkdeveloptool.git

Compile the ATF
===============

  > cd arm-trusted-firmware
  > make realclean
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31

  Or you can get the bl31.elf directly from Rockchip:
  cp rkbin/rk33/rk3399_bl31_v1.00.elf ../u-boot/bl31.elf

  Get bl31.elf in this step, copy it to U-Boot root dir:
  > cp bl31.elf ../u-boot/

Compile the U-Boot
==================

  > cd ../u-boot
  > export ARCH=arm64
  > export CROSS_COMPILE=aarch64-linux-gnu-
  > make evb-rk3399_defconfig
  for firefly-rk3399, use below instead:
  > make firefly-rk3399_defconfig
  > make
  > make u-boot.itb

  Get spl/u-boot-spl.bin and u-boot.itb in this step.

Compile the rkdeveloptool
=======================
  Follow instructions in latest README
  > cd ../rkdeveloptool
  > autoreconf -i
  > ./configure
  > make
  > sudo make install

  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
=================

Package the image for U-Boot SPL(option 1)
--------------------------------
  > cd ..
  > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img

  Get idbspl.img in this step.

Package the image for Rockchip miniloader(option 2)
------------------------------------------
  > cd ..
  > cp arm-trusted-firmware/build/rk3399/release/bl31.elf rkbin/rk33
  > ./rkbin/tools/trust_merger rkbin/tools/RK3399TRUST.ini
  > ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img

  Get trust.img and uboot.img in this step.

Flash the image to eMMC
=======================

Flash the image with U-Boot SPL(option 1)
-------------------------------
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
  > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
  > rkdeveloptool wl 64 u-boot/idbspl.img
  > rkdeveloptool wl 0x4000 u-boot/u-boot.itb
  > rkdeveloptool rd

Flash the image with Rockchip miniloader(option 2)
----------------------------------------
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
  > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
  > rkdeveloptool ul rkbin/rk33/rk3399_loader_v1.08.106.bin
  > rkdeveloptool wl 0x4000 u-boot/uboot.img
  > rkdeveloptool wl 0x6000 u-boot/trust.img
  > rkdeveloptool rd

You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
