    This commit add the support of encrypting image with aes
    in mkimage. To enable the ciphering, a node cipher with
    a reference to a key and IV (Initialization Vector) must
    be added to the its file. Then mkimage add the encrypted
    image to the FIT and add the key and IV to the u-boot

  • 245b1029e   bmp_logo: support CONFIG_DM_VIDEO ... Browse Code »

    in case of bmp_logo, the video_bmp driver is used for
    drawing a bmp logo. This driver supports only "full"
    bmp data. Adding a logo with the bmp_logo tool to
    u-boot binary adds currently only real data and drops
    the bmp header.

    This patch adds now the full bmp data to the u-boot
    binary, so video_bmp driver works with the logo embedded
    into u-boot.

    Fixed also some checkpatch error poping up with this
    patch.

    Some Intel SoCs from about 2016 boot using an internal microcontroller via
    an 'IFWI' image. This is a special format which can hold firmware images.
    In U-Boot's case it holds u-boot-tpl.bin.

    Add this tool, taken from coreboot, so that we can build bootable images
    on apollolake SoCs.

    This tool itself has no tests. Some amount of coverage will be provided by
    the binman tests that use it, so enable building the tool on sandbox.

    This adds a size check for SPL that can dynamically check generated
    SPL binaries (including devicetree) for a size limit that ensures
    this image plus global data, heap and stack fit in initial SRAM.

    Since some of these sizes are not available to make, a new host tool
    'spl_size_limit' is added that dumps the resulting maximum size for
    an SPL binary to stdout. This tool is used in toplevel Makefile to
    implement the size check on SPL binaries.

    Parts of the code are using C99 constructs (such as variables declared
    inside loops), but also GNU extensions (such as typeof), so using
    -std=gnu99 is necessary to build with older versions of gcc that don't
    default to building with gnu99.

    It fixes the following build failure:

    Especially on OpenEmbedded / Yocto Project ecosystem, it is very
    common each BSP to end providing their specific tools when they need

    The CRC16-CCITT checksum function is useful for space-constrained
    applications (such as obtaining a checksum across a 2KBit or 4KBit
    EEPROM) in boot applications. It has not been accessible from boot
    scripts until now (due to not having a dedicated command and not being
    supported by the hash infrstructure) limiting its applicability
    outside of custom commands.

    This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
    list of available hashes and adds a new crc16_ccitt_wd_buf() to make
    this possible.

  • 72239fc85   vboot: Add FIT_SIGNATURE_MAX_SIZE protection ... Browse Code »

    This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
    max size of a FIT header's totalsize field. The field is checked before
    signature checks are applied to protect from reading past the intended
    FIT regions.

    This field is not part of the vboot signature so it should be sanity
    checked. If the field is corrupted then the structure or string region
    reads may have unintended behavior, such as reading from device memory.
    A default value of 256MB is set and intended to support most max storage
    sizes.

  • 6915dcf35   tools: zynqmpimage: Add bif support ... Browse Code »

    The officially described way to generate boot.bin files for ZynqMP is to
    describe the contents of the target binary using a file of the "bif"
    format. This file then links to other files that all get packed into a
    bootable image.

    This patch adds support to read such a .bif file and generate a respective
    ZynqMP boot.bin file that can include the normal image and pmu files, but
    also supports image partitions now. This makes it a handy replacement for
    the proprietary "bootgen" utility that is currently used to generate
    boot.bin files with FSBL.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

    scripts/dtc/libfdt/libfdt_env.h from upstream DTC is suitable

    For compiling U-Boot, we need to override such system-dependent

    inclusion completely, but I do not want too many patches at one.

  • ac0201961   tools: provide a tool to convert a binary file to an include ... Browse Code »

    For testing EFI disk management we need an in-memory image of
    a disk.

    The tool file2include converts a file to a C include. The file
    is separated into strings of 8 bytes. Only the non-zero strings
    are written to the include. The output format has been designed
    to maintain readability.

    #define EFI_ST_DISK_IMG { 0x00010000, { \
    {0x000001b8, "\x94\x37\x69\xfc\x00\x00\x00\x00"}, /* .7i..... */ \
    {0x000001c0, "\x02\x00\x83\x02\x02\x00\x01\x00"}, /* ........ */ \

    As the disk image needed for testing contains mostly zeroes a high
    compression ratio can be attained.

  • b38ad663a   tools: use files from scripts/dtc/libfdt where possible ... Browse Code »

    Prior to this commit, tools/Makefile pulls all libfdt files from

    fdt_sw.c

    This commit changes them to #include ones from scripts/dtc/libfdt.

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

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

    The fdt_region.c is U-Boot own file. This is also borrowed from

    The pylibfdt is used by dtoc (and, indirectly by binman), but there
    is no reason why it must be generated in the tools/ directory.

    Recently, U-Boot switched over to the bundled DTC, and the directory
    structure under scripts/dtc/ now mirrors the upstream DTC project.
    So, scripts/dtc/pylibfdt is the best location.

    I also rewrote the Makefile in a cleaner Kbuild style.

    The scripts from the upstream have been moved as follows:

    lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
    lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

    The .i_shipped is coped to .i during building because the .i must be
    located in the objtree when we build it out of tree.

  • 3809e3027   Makefile: honor PYTHON configuration properly ... Browse Code »
    20

    On some systems `python` is `python3` (for instance, Archlinux). The
    `PYTHON` variable can be used to point to `python2` to have a successful
    build.

    The use of `PYTHON` is currently limited in the Makefile and needs to be
    extended in other places:

    First, pylibfdt is required to be a Python 2 binding (binman imports
    pylibfdt and is only compatible Python 2), so its setup.py needs to be
    called accordingly. An alternative would be to change the libfdt
    setup.py shebang to python2, but the binding is actually portable. Also,
    it would break on system where there is no such thing as `python2`.

    Secondly, the libfdt import checks need to be done against Python 2 as
    well since the Python 2 compiled modules (in this case _libdft.so) can
    not be imported from Python 3.

    Note on the libfdt imports: "@if ! PYTHONPATH=tools $(PYTHON) -c 'import
    libfdt'; then..." is probably simpler than the currently sub-optimal
    pipe.

  • 703ec9ddf   MIPS: Stop building position independent code ... Browse Code »
    1

    U-Boot has up until now built with -fpic for the MIPS architecture,
    producing position independent code which uses indirection through a
    global offset table, making relocation fairly straightforward as it
    simply involves patching up GOT entries.

    Using -fpic does however have some downsides. The biggest of these is
    that generated code is bloated in various ways. For example, function
    calls are indirected through the GOT & the t9 register:

    8f998064 lw t9,-32668(gp)
    0320f809 jalr t9

    Without -fpic the call is simply:

    0f803f01 jal be00fc04

    This is more compact & faster (due to the lack of the load & the
    dependency the jump has on its result). It is also easier to read &
    debug because the disassembly shows what function is being called,
    rather than just an offset from gp which would then have to be looked up
    in the ELF to discover the target function.

    Another disadvantage of -fpic is that each function begins with a
    sequence to calculate the value of the gp register, for example:

    3c1c0004 lui gp,0x4
    279c3384 addiu gp,gp,13188
    0399e021 addu gp,gp,t9

    Without using -fpic this sequence no longer appears at the start of each
    function, reducing code size considerably.

    This patch switches U-Boot from building with -fpic to building with
    -fno-pic, in order to gain the benefits described above. The cost of
    this is an extra step during the build process to extract relocation
    data from the ELF & write it into a new .rel section in a compact
    format, plus the added complexity of dealing with multiple types of
    relocation rather than the single type that applied to the GOT. The
    benefit is smaller, cleaner, more debuggable code. The relocate_code()
    function is reimplemented in C to handle the new relocation scheme,
    which also makes it easier to read & debug.

    Taking maltael_defconfig as an example the size of u-boot.bin built
    using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
    2.24.90) shrinks from 254KiB to 224KiB.
