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.

41f59f6853 microblaze: Build only DTBs for selected target
Adding more targets to repository requires some additional
changes not simply just adding config file, defconfig and dts.
This patch makes this process easier by building only
particular DTB which is selected via defconfig
that Makefile doesn't need to contain all dts files in the repository.

20434c8a0b microblaze: Add missing chosen node
fdtgrep requires /chosen node to be specified or at least more nodes which
stays in DTS to generate output.
Error message:
./tools/fdtgrep -b u-boot,dm-pre-reloc -RT dts/dt.dtb -n /chosen -O
dtb | ./tools/fdtgrep -r -O dtb - -o spl/u-boot-spl.dtb -P pinctrl-0 -P
pinctrl-names -P clocks -P clock-names -P interrupt-parent
Error: FDT_ERR_BADMAGIC

This patch add empty chosen node to keep fdtgrep happy and pass
compilation for in tree DTS file.

da58dec866 Various Makefiles: Add SPDX-License-Identifier tags
After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one.  This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

5957ac2a9f Makefile: Support include files for .dts files
Linux supports this, and if we are to have compatible device tree files,
U-Boot should also.

Avoid giving the device tree files access to U-Boot's include/ directory.
Only include/dt-bindings is accessible.

3284c8b8ca dts: generate multiple device tree blobs
It is convenient to have all device trees on the same SoC compiled.
It allows for later easy repackaging without the need to re-run
the make file.

  - Build device trees with the same SoC under arch/$(ARCH)/dts

  - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or
    DEVICE_TREE=... to dts/dt.dtb

5ab502cb89 dts: move device tree sources to arch/$(ARCH)/dts/
Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.
