Tom Rini 83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

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 ../rkflashtool
  > 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)
