7251c2d8bc dtc(1): Pull in fix for segfault-upon-error condition
Specifically, parse errors within a node would lead to a segfault due to
an unconditional dereference after emitting the error.

d37eb02eb9 dtc(1): Update to 1a79f5f26631
Highlights:
- Bugfix for order in which /delete-node/ and /delete-property/ are
  processed [0]
- /omit-if-no-ref/ support has been added (used only by U-Boot at this
  point, in theory)
- GPL dtc compat version bumped to 1.4.7
- Various small fixes and compatibility improvements

1a36f105a4 dtc(1): Update to 97d2d5715eeb45108cc60367fdf6bd5b2046b050
Notable fixes:
- Overlays may now be generated properly without -@
- /__local_fixups__ were not including unit address in their structure
- The error reporting a magic token was misleading, reporting
  "Bad magic token in header.  Got d00dfeed expected 0xd00dfeed"
  if the token was missing. This has been split out into a separate message.

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).

21d5d37ba4 dtc: update to upstream 227d6a3
- Report missing includes at the correct location.
- Add initial support for the -@ option emitting a symbol table.
- Add support for running tests with and without -@
- Add support for generating __fixups__ and __local_fixups__
- Attach the to-string transform to the node path.

be5d5a33e6 fdt: Expect strchr() to return a const char*
In C, strchr(3) returns a char*, whereas C++ defines two overloads:
* const char *strchr(const char*, int)
* char *strchr(char*, int)

Building fdt.cc (with the WITHOUT_GPL_DTC knob set) with libc++ 3.9.0 (imported
in r309124) was failing because libc++ r260377 added the first overload to
string.h, leading to failures such as:

    fdt.cc:1638:8: error: cannot initialize a variable of type 'char *' with an
    rvalue of type 'const char *'

Just define val as a const char* to fix it.

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.
