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.

How to Update U-Boot on Warp7 board
----------------------------------

Required software on the host PC:

- imx_usb_loader: https://github.com/boundarydevices/imx_usb_loader

- dfu-util: http://dfu-util.sourceforge.net/releases/ (if you are in a
Debian distribution then you can get it via libdfu-dev package)

- libusb: http://libusb.org/ (if you are in a Debian distribution
then you can get it via libusb-dev and libusb-1.0-0-dev)

In U-Boot folder, build U-Boot for Warp7:

$ make mrproper
$ make warp7_config
$ make

This will generate the U-Boot binary called u-boot.imx.

Put warp7 board in USB download mode: 

Remove the CPU board from the base board then put switch 2 in the upper
position

Connect a USB to serial adapter between the host PC and warp7

Connect a USB cable between the OTG warp7 port and the host PC

Copy u-boot.imx to the imx_usb_loader folder.

Load u-boot.imx via USB:

$ sudo ./imx_usb u-boot.imx

Then U-Boot should start and its messages will appear in the console program.

Open a terminal program such as minicom

Use the default environment variables:

=> env default -f -a
=> saveenv

Run the DFU command:
=> dfu 0 mmc 0

Transfer u-boot.imx that will be flashed into the eMMC:

$ sudo dfu-util -D u-boot.imx -a boot

Then on the U-Boot prompt the following message should be seen after a
successful upgrade:

#DOWNLOAD ... OK
Ctrl+C to exit ...

Remove power from the warp7 board.

Put warp7 board into normal boot mode (put the switch 2 in the lower position)

Power up the board and the new updated U-Boot should boot from eMMC
