  • Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • The current rules have the .dtb files build in a different directory
    from the .dts files. This patch changes openrisc to use the generic dtb
    rule which builds .dtb files in the same directory as the source .dts.

    This requires renaming arch/openrisc/boot/Makefile to
    arch/openrisc/boot/dts/Makefile, and updating arch/openrisc/Makefile to
    call the new Makefile.

  • This hooks dtc into Kbuild's dependency system.

    Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
    tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
    lack of this feature recently caused me to have very confusing "git
    bisect" results.

    For ARM, it's obvious what to add to $(targets). I'm not familiar enough
    with other architectures to know what to add there. Powerpc appears to
    already add various .dtb files into $(targets), but the other archs may
    need something added to $(targets) to work.

  • The OpenRISC architecture uses the device tree infrastructure for the
    platform description. This is currently limited to having a device tree
    built into the kernel, but work is underway within the OpenRISC project
    to define how this device tree blob should be passed into the kernel from
    an external resource.

    Patch contains a single example DTS file to go with the defconfig for
    or1ksim.
