  • a8de1304b   libfdt: define INT32_MAX and UINT32_MAX in libfdt_env.h ... Browse Code »

    The DTC v1.5.1 added references to (U)INT32_MAX.

    This is no problem for user-space programs since defines
    (U)INT32_MAX along with (u)int32_t.

    For the kernel space, libfdt_env.h needs to be adjusted before we
    pull in the changes.

    In the kernel, we usually use s/u32 instead of (u)int32_t for the
    fixed-width types.

    Accordingly, we already have S/U32_MAX for their max values.
    So, we should not add (U)INT32_MAX to any more.

    Instead, add them to the in-kernel libfdt_env.h to compile the
    latest libfdt.

    The next update of libfdt has a new dependency on INT_MAX. Update the
    instances of libfdt_env.h in the kernel to either include the necessary
    header with the definition or define it locally.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    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

  • ab2538398   of/lib: Allow scripts/dtc/libfdt to be used from kernel code ... Browse Code »

    libfdt is part of the device tree support in scripts/dtc/libfdt. For
    some platforms that use the Device Tree, we want to be able to edit
    the flattened device tree form.

    We don't want to burden kernel builds that do not require it, so we
    gate compilation of libfdt files with CONFIG_LIBFDT. So if it is
    needed, you need to do this in your Kconfig:

    select LIBFDT

    And in the Makefile of the code using libfdt something like:

    ccflags-y := -I$(src)/../../../scripts/dtc/libfdt
