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

  • 01286329b   kbuild: rename SRCTREE to srctree ... Browse Code »

    Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for
    pointing to the top of source directory.
    (No difference between the two.)

    In Kbuild style, $(srctree) is used for instead.
    This commit renames SRCTREE to srctree and deletes the
    defition of SRCTREE.

    Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c,
    doc/DocBook/Makefile should be keep.

  • 9e4140329   kbuild: change out-of-tree build ... Browse Code »
    44

    This commit changes the working directory
    where the build process occurs.

    Before this commit, build process occurred under the source
    tree for both in-tree and out-of-tree build.

    That's why we needed to add $(obj) prefix to all generated
    files in makefiles like follows:
    $(obj)u-boot.bin: $(obj)u-boot

    Here, $(obj) is empty for in-tree build, whereas it points
    to the output directory for out-of-tree build.

    And our old build system changes the current working directory
    with "make -C " syntax when descending into the
    sub-directories.

    On the other hand, Kbuild uses a different idea
    to handle out-of-tree build and directory descending.

    The build process of Kbuild always occurs under the output tree.
    When "O=dir/to/store/output/files" is given, the build system
    changes the current working directory to that directory and
    restarts the make.

    Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
    syntax for descending into sub-directories.
    (We can write it like "make $(obj)=" with a shorthand.)
    This means the current working directory is always the top
    of the output directory.

  • 1affd4d4a   cam_enc_4xx: Move CONFIG_SPL_PAD_TO to a config header ... Browse Code »

    For most boards which define CONFIG_SPL_PAD_TO,
    it is defined in config header files.
    Currently, there exists only one exception, cam_enc_4xx board.

    This patch moves CONFIG_SPL_PAD_TO definition
    from board/ait/cam_enc_4xx/config.mk
    to include/configs/cam_enc_4xx.h.

    With this modification, we can delete a glue code
    in the top level config.mk:

    ifneq ($(CONFIG_SPL_PAD_TO),)
    CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO)
    endif

  • dfe64e2c8   mtd: resync with Linux-3.7.1 ... Browse Code »
    34

    This patch is essentially an update of u-boot MTD subsystem to
    the state of Linux-3.7.1 with exclusion of some bits:

    - the update is concentrated on NAND, no onenand or CFI/NOR/SPI
    flashes interfaces are updated EXCEPT for API changes.

    - new large NAND chips support is there, though some updates
    have got in Linux-3.8.-rc1, (which will follow on top of this patch).

    To produce this update I used tag v3.7.1 of linux-stable repository.

    The update was made using application of relevant patches,
    with changes relevant to U-Boot-only stuff sticked together
    to keep bisectability. Then all changes were grouped together
    to this patch.

  • 3929fb0a1   Replace __bss_end__ with __bss_end ... Browse Code »

    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.

    This was already used by some SPL targets, and allows the pad amount to
    be specified by board config headers rather than only in makefile
    fragments.

    Also supply a pad-to of zero if the variable is undefined. It works
    without this, but this avoids relying on undocumented behavior.
