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.

README 

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:
