0a65536cab make_dtb.sh: Use $CPP instead of assuming that cpp is in $PATH
This fixes building in CheriBSD with a strict tmp path since we don't
bootstrap a cpp but pass the full path to clang-cpp instead.

While touching this file also fix all shellcheck warnings in make_dtb.sh.

5695558451 make_dtb: Always add root directory in the include path
Some arch like arm and arm64 share DTS files, add the root dts directory
to the include paths.

c2f5940db3 Add dtb overlays support
DTB Overlays are useful to change/add nodes to a dtb without the need to
modify it.
Add support for building dtbo during buildkernel.
The goal of DTBO present in the FreeBSD source tree is to fill a gap in
time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months
we can add a DTBO in tree in the meantime.
This is not for adding DTBO for capes/hat/addon boards, those will be
better to put in a ports.
This is also not for enabling a i2c/spi/pwm controller on certain pins,
each user have a different use case for those (which pins to use etc ...)
and we cannot have all possible configuration.

Add a dtbo for sun8i-h3-sid which add the SID node missing in upstream dts.

fe267a5590 sys: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

56d78e82f0 Turns out this .if evaluated not in the context of the makedtb target
sometimes due to Makefile expansion rules. Make the test for things
being NULL elsewhere...

0edb735169 Allow FDT_DTS_FILE to be a list, either in the makedtb target, or in a
kernel config file. If you also want to have a static DTB compiled
into your kernel, however, it cannot be a list. We have no mechanism
in the kernel for picking one, so that doesn't make sense and will
result in a compile-time error.

eeb913c99f Integrate device-tree upstream files into the build process:
(1) Invoke cpp to bring in files via #include (although the old
    /include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
    when building.
(3) move all dts* files from sys/boot/fdt/dts to
    sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
    so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
    significant issues not easily addressed by those unfamiliar with
    the code.
