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.

Latest wandboard hardware revision is revd1, which brings the following
new features:
- PFUZE100 PMIC
- AR8035 Ethernet PHY
- Upgrade Wifi/BT chip to BCM4339/BCM43430.
The detection mechanism is to probe the PMIC and when it is
found, then the revision of the board is revd1.
As the detection is done via PMIC, we need to print the board version
at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need
to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.
Make the necessary adjustments for the AR8035 PHY to work on revd1.

However, on wandboard design we need some additional configuration,
such as enabling the 125 MHz AR8031 output that needs to be done
in the board file.

In Linux Kernel, defconfig files are located under

It works in Linux Kernel since ARCH is always given from the

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.

By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.
