  • 8137af19e   arm64: Add tool to statically apply RELA relocations ... Browse Code »

    ARM64 uses the newer RELA-style relocations rather than the older REL.
    RELA relocations have an addend in the relocation struct, rather than
    expecting the loader to read a value from the location to be updated.

    While this is beneficial for ordinary program loading, it's problematic
    for U-Boot because the location to be updated starts out with zero,
    rather than a pre-relocation value. Since we need to be able to run C
    code before relocation, we need a tool to apply the relocations at
    build time.

    In theory this tool is applicable to other newer architectures (mainly
    64-bit), but currently the only relocations it supports are for arm64,
    and it assumes a 64-bit little-endian target. If the latter limitation
    is ever to be changed, we'll need a way to tell the tool what format
    the image is in. Eventually this may be replaced by a tool that uses
    libelf or similar and operates directly on the ELF file. I've written
    some code for such an approach but libelf does not make it easy to poke
    addresses by memory address (rather than by section), and I was
    hesitant to write code to manually parse the program headers and do the
    update outside of libelf (or to iterate over sections) -- especially
    since it wouldn't get test coverage on things like binaries with
    multiple PT_LOAD segments. This should be good enough for now to let
    the manual relocation stuff be removed from the arm64 patches.

  • 0fcac1abd   SPL: EXYNOS: Prepare for variable size SPL support ... Browse Code »

    When variable size SPL is used, the BL1 expects the SPL to be
    encapsulated differently: instead of putting the checksum at a fixed
    offset in the SPL blob, prepend the blob with a header including the
    size and the checksum.

    The enhancements include
    - adding a command line option, '--vs' to indicate the need for the
    variable size encapsulation
    - padding the fixed size encapsulated blob with 0xff instead of random
    memory contents
    - do not silently truncate the input file, report error instead
    - no need to explicitly closing files/freeing memory, this all happens
    on exit; removing cleanups it makes code clearer
    - profuse commenting
    - modify Makefile to allow enabling the new feature per board

  • 5b5a82eb7   ARM: mxs: tools: Fix errno handling in strtoul() invocation ... Browse Code »

    According to NOTE in strtoul(3), the errno must be zeroed before strtoul()
    is called. Zero the errno. The NOTE reads as such:

    Since strtoul() can legitimately return 0 or ULONG_MAX (ULLONG_MAX for
    strtoull()) on both success and failure, the calling program should set
    errno to 0 before the call, and then determine if an error occurred
    by checking whether errno has a nonzero value after the call.

    This issue was detected on Fedora 19 with glibc 2.17 .

  • dd88ab325   Makefile: Move some scripts imported from Linux ... Browse Code »

    We have some scripts imported from Linux Kernel:
    setlocalversion, checkstack.pl, checkpatch.pl, cleanpatch

    They are located under tools/ directory in U-Boot now.
    But they were originally located under scripts/ directory
    in Linux Kernel.

    This commit moves them to the original location.

    It is true that binutils-version.sh and dtc-version.sh
    do not originate in Linux Kernel, but they should
    be moved by analogy to gcc-version.sh.

  • a804b5ce2   Add dumpimage, a tool to extract data from U-Boot images ... Browse Code »

    Given a multi-file image created through the mkimage's -d option:

    $ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
    multi.img

    Image Name: x86
    Created: Thu Jul 25 10:29:13 2013
    Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
    Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
    Load Address: 00000000
    Entry Point: 00000000
    Contents:
    Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
    Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
    Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB

    It is possible to perform the innverse operation -- extracting any file from
    the image -- by using the dumpimage's -i option:

    $ dumpimage -i multi.img -p 2 System.map

    Although it's feasible to retrieve "data files" from image through scripting,
    the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
    is cumbersome and unreliable -- once you must keep track of file sizes inside
    the image. Furthermore, extracting data files using "dumpimage" tool is faster
    than through scripting.

  • f86ed6a8d   tools: moved code common to all image tools to a separated module. ... Browse Code »
    43

    In order to avoid duplicating code and keep only one point of modification,
    the functions, structs and defines useful for "dumpimage" were moved from
    "mkimage" to a common module called "imagetool".

    This modification also weakens the coupling between image types (FIT, IMX, MXS,
    and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
    "imagetool" through register_image_tool() function, while the image types
    register themselves within an image tool using the register_image_type()
    function:

    +---------------+
    +------| fit_image |
    +--------------+ +-----------+ | +---------------+
    | mkimage |--------> | | | |

  • 8426d8b08   buildman: make board selector argument a regex ... Browse Code »

    A common use-case is to build all boards for a particular SoC. This can
    be achieved by:

    ./tools/buildman/buildman -b mainline_dev tegra20

    However, when the SoC is a member of a family of SoCs, and each SoC has
    a different name, it would be even more useful to build all boards for
    every SoC in that family. This currently isn't possible since buildman's
    board selection command-line arguments are compared to board definitions
    using pure string equality.

    To enable this, compare using a regex match instead. This matches
    MAKEALL's handling of command-line arguments. This enables:

    (all Tegra)
    ./tools/buildman/buildman -b mainline_dev tegra

    (all Tegra)
    ./tools/buildman/buildman -b mainline_dev '^tegra.*$'

    (all Tegra20, Tegra30 boards, but not Tegra114)
    ./tools/buildman/buildman -b mainline_dev 'tegra[23]'

    Sometimes a commit should have notes enclosed with it rather
    than withing the cover letter -- possibly even because there
    is no cover letter. Add a 'Commit-notes' tag, similar to the
    'Series-notes' one; lines between this tag and the next END
    line are inserted in the patch right after the '---' commit
    delimiter.

  • 8bb2bddc2   buildman: don't fail --list-toolchains when toolchains fail ... Browse Code »

    When a toolchain invocation fails, an exception is thrown but not caught
    which then aborts the entire toolchain detection process. To solve this,
    request that exceptions not be thrown, since the toolchain init code
    already error-checks the command result. This solves e.g.:

    - found '/usr/bin/winegcc'
    Traceback (most recent call last):
    ...
    Exception: Error running '/usr/bin/winegcc --version'
