    Various files are needlessly rebuilt every time due to the version and
    build time changing. As version.h is not actually needed, remove the
    include.

  • 0060517ae   cppcheck cleanup: fix nullPointer errors ... Browse Code »

    There are a number of places where U-Boot intentionally and legally
    accesses physical address 0x0000, for example when installing
    exception vectors on systems where these are located in low memory.

    Add "cppcheck-suppress nullPointer" comments to silence cppcheck
    where this is intentional and legal.

  • 2e07c249a   kconfig: arm: introduce symbol for ARM CPUs ... Browse Code »
    220

    This commit introduces a Kconfig symbol for each ARM CPU:
    CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
    CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
    Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
    for CPU_ARM1176 and CPU_V7.

    For each target, the corresponding CPU is selected and the definition of
    SYS_CPU in the corresponding Kconfig file is removed.

    Also, it removes redundant "string" type in some Kconfig files.

    44

    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//
    }
    '

  • 93d4334f7   Add board MAINTAINERS files ... Browse Code »

    We have switched to Kconfig and the boards.cfg file is going to
    be removed. We have to retrieve the board status and maintainers
    information from it.

    The MAINTAINERS format as in Linux Kernel would be nice
    because we can crib the scripts/get_maintainer.pl script.

    After some discussion, we chose to put a MAINTAINERS file under each
    board directory, not the top-level one because we want to collect
    relevant information for a board into a single place.

    TODO:
    Modify get_maintainer.pl to scan multiple MAINTAINERS files.

  • 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/.

  • 464c79207   punt unused clean/distclean targets ... Browse Code »

    The top level Makefile does not do any recursion into subdirs when
    cleaning, so these clean/distclean targets in random arch/board dirs
    never get used. Punt them all.

    MAKEALL didn't report any errors related to this that I could see.

  • 386393c68   scb9328: Add ARM relocation support ... Browse Code »

    This patch fixes compiler errors due to missing definitions of
    CONFIG_SYS_SDRAM_BASE and CONFIG_SYS_INIT_SP_ADDR.

    It also does some cleanup: CONFIG_SYS_TEXT_BASE was moved to scb9328.h,
    obsolete config.mk was removed. The scb9328 board has 1 DRAM bank, so don't
    ask for more banks. CONFIG_NR_DRAM_BANKS will ever be 1.

  • 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.

  • 14d0a02a1   Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE ... Browse Code »

    The change is currently needed to be able to remove the board
    configuration scripting from the top level Makefile and replace it by
    a simple, table driven script.

    Moving this configuration setting into the "CONFIG_*" name space is
    also desirable because it is needed if we ever should move forward to
    a Kconfig driven configuration system.

  • f62fb9994   Fix all linker script to handle all rodata sections ... Browse Code »

    A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
    which needs to be added the the linker script. Instead of just adding this
    one section, we use a wildcard ".rodata*" to get all rodata linker section
    gcc has now and might add in the future.

    However, '*(.rodata*)' by itself will result in sub-optimal section
    ordering. The sections will be sorted by object file, which causes extra
    padding between the unaligned rodata.str.1.1 of one object file and the
    aligned rodata of the next object file. This is easy to fix by using the
    SORT_BY_ALIGNMENT command.

    This patch has not be tested one most of the boards modified. Some boards
    have a linker script that looks something like this:

    *(.text)
    . = ALIGN(16);
    *(.rodata)
    *(.rodata.str1.4)
    *(.eh_frame)

    I change this to:

    *(.text)
    . = ALIGN(16);
    *(.eh_frame)
    *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

    This means the start of rodata will no longer be 16 bytes aligned.
    However, the boundary between text and rodata/eh_frame is still aligned to
    16 bytes, which is what I think the real purpose of the ALIGN call is.

  • 64134f011   Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections ... Browse Code »
    21

    With recent toolchain versions, some boards would not build because
    or errors like this one (here for ocotea board when building with
    ELDK 4.2 beta):
    ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

    For many boards, the .bss section is big enough that it wraps around
    at the end of the address space (0xFFFFFFFF), so the problem will not
    be visible unless you use a 64 bit tool chain for development. On
    some boards however, changes to the code size (due to different
    optimizations) we bail out with section overlaps like above.

    The fix is to add the NOLOAD attribute to the .bss and .sbss
    sections, telling the linker that .bss does not consume any space in
    the image.

  • f93286397   Add support for a saving build objects in a separate directory. ... Browse Code »

    Modifications are based on the linux kernel approach and
    support two use cases:

    1) Add O= to the make command line
    'make O=/tmp/build all'

    2) Set environement variable BUILD_DIR to point to the desired location
    'export BUILD_DIR=/tmp/build'
    'make'

    The second approach can also be used with a MAKEALL script
    'export BUILD_DIR=/tmp/build'
    './MAKEALL'

    Command line 'O=' setting overrides BUILD_DIR environent variable.

    When none of the above methods is used the local build is performed and
    the object files are placed in the source directory.
