  • 61304dbec   cmd: add a new command "config" to show .config contents ... Browse Code »

    This feature is inspired by /proc/config.gz of Linux. In Linux,
    if CONFIG_IKCONFIG is enabled, the ".config" file contents are
    embedded in the kernel image. If CONFIG_IKCONFIG_PROC is also
    enabled, the ".config" contents are exposed to /proc/config.gz.
    Users can do "zcat /proc/config.gz" to check which config options
    are enabled on the running kernel image.

    The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
    the ".config" contents are compressed and saved in the U-Boot image,
    then printed by the new command "config".

    The usage is quite simple. Enable CONFIG_CMD_CONFIG, then run
    > config
    from the command line interface. The ".config" contents will be
    printed on the console.

    This feature increases the U-Boot image size by about 4KB (this is
    mostly due to the gzip-compressed .config file). By default, it is
    enabled only for Sandbox because we do not care about the memory
    footprint on it. Of course, this feature is architecture agnostic,
    so you can enable it on any board if the image size increase is
    acceptable for you.

  • a1b6b0a9c   arm: mvebu: Implement secure boot ... Browse Code »

    The patch implements secure booting for the mvebu architecture.

    This includes:
    - The addition of secure headers and all needed signatures and keys in
    mkimage
    - Commands capable of writing the board's efuses to both write the
    needed cryptographic data and enable the secure booting mechanism
    - The creation of convenience text files containing the necessary
    commands to write the efuses

    The KAK and CSK keys are expected to reside in the files kwb_kak.key and
    kwb_csk.key (OpenSSL 2048 bit private keys) in the top-level directory.

  • 1f6a66480   Makefile: preserve output for images that can contain HAB Blocks ... Browse Code »

    To being able to sign created binaries, we need to know the HAB Blocks
    for that image. Especially for the imximage type the HAB Blocks are
    only available during creation of the image. We want to preserve the
    information until we get to sign the files.
    In the verbose case we still get them printed out instead of writing
    to log files.

    v2-Changes:
    - No usage of MKIMAGEOUTPUT_$(@F) macro.
    - Predefine default value /dev/null in every involved Makefile.

    26

    When we want to use Secure Boot with HAB from SPL over U-Boot.img,
    we need to append the IVT to the image and leave space for the CSF.
    Images generated as firmware_ivt can directly be signed using the
    Freescale code signing tool. For creation of a CSF, mkimage outputs
    the correct HAB Blocks for the image.
    The changes to the usual firmware image class are quite small,
    that is why I implemented that directly into the default_image.

  • 1bd876301   Makefile: Add a target to create the .cfg files ... Browse Code »

    A common requirement when converting CONFIG options to Kconfig is to check
    that the effective configuration has not changed due to the conversion. Add
    a target which creates this configuration (in the form of u-boot.cfg) but
    does not build U-Boot. This speeds up the checking.

  • e19b0fb48   kbuild: generate u-boot.cfg as a byproduct of include/autoconf.mk ... Browse Code »
    14

    Our build system still parses ad-hoc CONFIG options in header files
    and generates include/autoconf.mk so that Makefiles can reference
    them. This gimmick was introduced in the pre-Kconfig days and will
    be kept until Kconfig migration is completed.

    The include/autoconf.mk is generated like follows:

    [1] Preprocess include/common.h with -DDO_DEPS_ONLY and
    retrieve macros into include/autoconf.mk.tmp
    [2] Reformat include/autoconf.mk.dep into include/autoconf.mk
    with tools/scripts/define2mk.sed script
    [3] Remove include/autoconf.mk.tmp

    Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is
    also generated by preprocessing include/config.h with -DDO_DEPS_ONLY.
    In other words, there is much overlap among include/autoconf.mk and
    u-boot.cfg build rules.

    So, the idea is to split the build rule of include/autoconf.mk
    into two stages. The first preprocesses headers into u-boot.cfg.
    The second parses the u-boot.cfg into include/autoconf.mk. The
    build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

    I am going to move the build rule of u-boot.cfg. Before that,
    no_new_adhoc_configs_check must be tweaked to not depend on it.

    The ad-hoc option check can be done at the end of build, along
    with other checks.

  • a6c130978   Makefile: rm u-boot.cfg dependencies are missing ... Browse Code »

    Prior to the previous patch, a freshly created .u-boot.cfg.cmd may not
    correctly represent all dependencies for u-boot.cfg. The previous change
    only solved this issue for fresh builds; when performing an incremental
    build, the deficient .u-boot.cfg.cmd is already present, so u-boot.cfg
    is not rebuilt, and hence .u-boot.cfg.cmd is not rebuilt with the correct
    content.

    Solve this by explicitly detecting when the dependency file .u-boot.cfg.d
    has not been integrated into .u-boot.cfg.cmd, and force u-boot.cfg to be
    rebuilt in this case by deleting it first. This is possible since
    if_changed_dep will always delete .u-boot.cfg.d when it executes
    successfully, so its presence means either that the previous build was
    made by a source tree that contained a Makefile that didn't include the
    previous patch, or that the build failed part way through executing
    if_changed_dep for u-boot.cfg. Forcing a rebuild of u-boot.cfg is required
    in the former case, and will cause no additional work in the latter case,
    since the file would be rebuilt anyway for the same reason it was being
    rebuilt by the previous build.

  • fcd29a4d0   Makefile: use if_change_dep for u-boot.cfg ... Browse Code »

    cmd_cpp_cfg generates a dependency output, but because it's invoked using
    if_changed rather than if_changed_dep, that dependency file is ignored.
    This results in Kbuild not knowing about which files u-boot.cfg depends
    on, so it may not be rebuilt when required.

    A practical result of this is that u-boot.cfg may continue to reference
    CONFIG_ options that no longer exist in the source tree, and this can
    cause the adhoc config options check to fail.

    This change modifies Makefile to use if_changed_dep, which in turn causes
    all dependencies to be known to the next make invocation.

    support more flexible configuration if new features (DDR4, multiple

    Meantime, reuse common MMDC driver for LS1012ARDB/LS1012AQDS/
    LS1012AFRDM.
