After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.
At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.
A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.
It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:
tegra
sunxi
x86
The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

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.

Now that binman is able to recognize the Video BIOS Table entry,
add such one in the u-boot.dtsi.

Since we now have the file names configurable via Kconfig for the flash
descriptor and intel-me files, add these from Kconfig in the corresponding
dts nodes.

When building for 64-bit we need to put an SPL binary into the image. Update
the binman image description to reflect this.

Change x86 boards to use binman to produce the ROM. This involves adding the
image definition to the device tree and using it in the Makefile. The
existing ifdtool features are no-longer needed.
Note that the u-boot.dtsi file is common and is used for all x86 boards which
use microcode. A separate emulation-u-boot-dtsi is used for the others.
