  • 461be2f96   kconfig: remove redundant "string" type in arch and board Kconfigs ... Browse Code »
    43

    Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
    are specified in arch/Kconfig.

    We can delete the ones in arch and board Kconfig files.

    This commit can be easily reproduced by the following command:

    find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
    /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//
    }
    '

  • 00a2517fc   nios2: Fix printf size_t format related warnings (again...) ... Browse Code »
    43

    When compiling the current code on GCC 4.8.3, the following warnings
    appear:

    warning: format '%zu' expects argument of type 'size_t', but argument
    2 has type 'long unsigned int' [-Wformat=]

    There were many mails about such warnings on different architectures.
    This patch limits itself to the nios2 architecture.

    The problem is that for the size_t (%zu, %zd, ...) arguments of
    printf GCC does not verify the type match to size_t type. It verifies
    the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if
    size_t is defined different from __SIZE_TYPE__ - warnings inevitably
    appear.

    There is a comment by Thomas Chou to the (rejected) patch:
    http://patchwork.ozlabs.org/patch/272102/
    which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2)
    expect size_t to be "unsigned long" and the newer expect it to be
    "unsigned int". Thus, no matter how we define size_t - either way
    warnings appear when using some GCC version.

    By rejecting that patch, a choice was made to prefer older GCC versions
    and leave the warnings when building with the newer toolchains.
    Personally, I disagree with this choice...

    In any case, this patch proposes a way to fix the warnings for any GCC
    version. Just define size_t using the __SIZE_TYPE__ compiler-defined
    type and the type verification will pass.

    I tested that this fixes the warning on GCC 4.8.3. I don't have an
    older toolchain to test with, but __SIZE_TYPE__ was definitely defined
    in GCC 3.4.6, so it should work there too.

  • dd84058d2   kconfig: add board Kconfig and defconfig files ... Browse Code »

    This commit adds:
    - arch/${ARCH}/Kconfig
    provide a menu to select target boards
    - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
    - configs/${TARGET_BOARD}_defconfig
    default setting of each board

    (This commit was automatically generated by a conversion script
    based on boards.cfg)

    In Linux Kernel, defconfig files are located under
    arch/${ARCH}/configs/ directory.
    It works in Linux Kernel since ARCH is always given from the
    command line for cross compile.

    But in U-Boot, ARCH is not given from the command line.
    Which means we cannot know ARCH until the board configuration is done.
    That is why all the "*_defconfig" files should be gathered into a
    single directory ./configs/.

    gd->bd->bi_baudrate is a copy of gd->baudrate.

    Since baudrate is a common feature for all architectures,
    keep gd->baudrate only.

    It is true that bi_baudrate was passed to the kernel in that structure
    but it was a long time ago.

    Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It
    requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before
    calling it again with flag set to BOOTM_STATE_OS_GO.
    Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will
    require a complete refactoring later on.

  • 983c72f47   Clarify bootm OS arguments ... Browse Code »

    At present the arguments to bootm are processed in a somewhat confusing
    way. Sub-functions must know how many arguments their calling functions
    have processed, and the OS boot function must also have this information.
    Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
    the same way.

    Adjust the code so that arguments are removed from the list before calling
    a sub-function. This means that all functions can know that argv[0] is the
    first argument of which they need to take notice.

  • 186528646   Introduce generic link section.h symbol files ... Browse Code »

    We create a separate header file for link symbols defined by the link
    scripts. It is helpful to have these all in one place and try to
    make them common across architectures. Since Linux already has a similar
    file, we bring this in even though many of the symbols there are not
    relevant to us.

    Each architecture has its own asm/sections.h where symbols specifc to
    that architecture can be added. For now everything except AVR32 just
    includes the generic header.

    One change is needed in arch/avr32/lib/board.c to make this conversion
    work.

    Note this is a tree-wide change affecting multiple architectures.

    At present we use __bss_start, but mostly __bss_end__. This seems
    inconsistent and in a number of places __bss_end is used instead.

    Change to use __bss_end for the BSS end symbol throughout U-Boot. This
    makes it possible to use the asm-generic/sections.h file on all
    archs.

    Refactor linker-generated array code so that symbols
    which were previously linker-generated are now compiler-
    generated. This causes relocation records of type
    R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
    code which uses LGA able to run before relocation as
    well as after.

    Note: this affects more than ARM targets, as linker-
    lists span possibly all target architectures, notably
    PowerPC.
