1631f21745 dtc: remove unknown option printf, since getopt will print it
Since we don't set opterr to 0, getopt prints a message when it
encounters an unknown/invalid option. We therefore don't need to
print our own message in the default handler.

aac4229aac Pull in latest fixes from dtc, up to 0060471
This includes a small battery of /memreserve/ fixes to make sure dtc is
properly writing these regions into the output file and reading them back
out.

As of this update, dtc will now also assume common defaults for -I/-O if
only one is specified; namely, dts for one implies dtb for the other and
vice versa (Requested by: jhibbits, preserves GPL dtc behavior too).

e69f393430 dtc(1): Update to upstream 006664a
Highlights:

- Passing "-" to -o will now cause output to go to stdout
- Path-based syntactic sugar for overlays is now accepted. This looks like:

/dts-v1/;
/plugin/;

&{/soc} {
    sid: eeprom@1c14000 {
        compatible = "allwinner,sun8i-h3-sid";
        reg = <0x1c14000 0x400>;
        status = "okay";
    };
};

ca84c67cd0 dtc(1): Update to upstream ea3c233
Highlights of this update:
- /__local_fixups__ is now generated to be GPL dtc and libfdt compliant
- Compiling with -@ will now cause dtc to assign phandles to all labelled
  nodes
- /include/ and /incbin/ now handle absolute paths correctly
- The manpage now has information about overlays, including how to apply
  them and how to generate them
- Syntactic sugar for overlays is now supported, allowing an overlay DTS
  like:

=
/dts-v1/;
/plugin/;

&foo {
    foo,status = "okay";
};
=

to generate a fragment targetting <&foo>.

1de7b4b805 various: 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.

b2dba1f64b dtc: Update to upstream 9ce35ff8
- Add "compatible with gpl dtc X.Y.Z" to version output so U-Boot doesn't complain
 - Fix cross reference node

This fixes some Allwinner DTS (and probably others).

a0706eb457 Lots of improvements to the BSD-licensed dtc
- Various fixes to includes (including recursive includes)
- Lots of testing that the output exactly matches GPL'd dtc
- Lots of bug fixes to merging
- Fix incorrect mmap usage
- Ad-hoc memory management replaced with C++11 unique_ptr and similar

Patrick Wildt has successfully run many (all?) of the GPL dtc test suite.

af0dd31fc4 Import new (BSDL) device tree compiler. Now built by default, so that it can't
be used on the host system (and not installed on the device, if required).  The
GPL'd one is still available if there are any devices that need it (make
universe passes with it, including kernels that use fdt, but there may be some
out-of-tree ones).  WITH_GPL_DTC can be used to select the old one, for now.

Probably won't be MFC'd, but we'll remove the GPL'd version in head after the
new one has had a lot more testing and ship it in 10.0.
