  • b08c8c487   libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h> ... Browse Code »
    42

    Thomas reported U-Boot failed to build host tools if libfdt-devel
    package is installed because tools include libfdt headers from
    /usr/include/ instead of using internal ones.

    This commit moves the header code:
    include/libfdt.h -> include/linux/libfdt.h
    include/libfdt_env.h -> include/linux/libfdt_env.h

    and replaces include directives:
    #include -> #include
    #include -> #include

  • 50a327ded   lib: libfdt: wrap scripts/dtc/libfdt/* where possible ... Browse Code »

    lib/libfdt/ and scripts/dtc/libfdt have the same copies for the
    followings 6 files:
    fdt.c fdt_addresses.c fdt_empty_tree.c fdt_overlay.c fdt_strerr.c
    fdt_sw.c

    Make them a wrapper of scripts/dtc/libfdt/*. This is exactly what
    Linux does to sync libfdt. In order to make is possible, import
    and from Linux 4.14-rc5.

    Unfortunately, U-Boot locally modified the following 3 files:
    fdt_ro.c fdt_wip.c fdt_rw.c

    The fdt_region.c is U-Boot own file.

    I did not touch them in order to avoid unpredictable impact.

  • ddf67f713   libfdt: Add overlay application function ... Browse Code »

    The device tree overlays are a good way to deal with user-modifyable
    boards or boards with some kind of an expansion mechanism where we can
    easily plug new board in (like the BBB, the Raspberry Pi or the CHIP).

    Add a new function to merge overlays with a base device tree.

    This brings in changes up to commit f9e91a48 in the libfdt repo.
    Mostly this is whitespace/minor changes. But there are a few new
    features:

    - fdt_size_cells() and fdt_address_cells()
    - fdt_resize()

  • c71b64f36   libfdt: Add helper function to create a trivial, empty tree ... Browse Code »

    The libfdt read/write functions are now usable enough that it's become a
    moderately common pattern to use them to build and manipulate a device
    tree from scratch. For example, we do so ourself in our rw_tree1 testcase,
    and qemu is starting to use this model when building device trees for some
    targets such as e500.

    However, the read/write functions require some sort of valid tree to begin
    with, so this necessitates either having a trivial canned dtb to begin with
    or, more commonly, creating an empty tree using the serial-write functions
    first.

    This patch adds a helper function which uses the serial-write functions to
    create a trivial, empty but complete and valid tree in a supplied buffer,
    ready for manipulation with the read/write functions.

    From git://git.jdl.com/software/dtc.git patch hash be6026838 with
    adaptations to include/libfdt.h and lib/libfdt/Makefile for the U-Boot
    environment.

  • 6d8962e81   Switch from archive libraries to partial linking ... Browse Code »

    Before this commit, weak symbols were not overridden by non-weak symbols
    found in archive libraries when linking with recent versions of
    binutils. As stated in the System V ABI, "the link editor does not
    extract archive members to resolve undefined weak symbols".

    This commit changes all Makefiles to use partial linking (ld -r) instead
    of creating library archives, which forces all symbols to participate in
    linking, allowing non-weak symbols to override weak symbols as intended.
    This approach is also used by Linux, from which the gmake function
    cmd_link_o_target (defined in config.mk and used in all Makefiles) is
    inspired.

    The name of each former library archive is preserved except for
    extensions which change from ".a" to ".o". This commit updates
    references accordingly where needed, in particular in some linker
    scripts.

    This commit reveals board configurations that exclude some features but
    include source files that depend these disabled features in the build,
    resulting in undefined symbols. Known such cases include:
    - disabling CMD_NET but not CMD_NFS;
    - enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
