  • e5a504eb3   MAINTAINERS: comment out invalid maintainers ... Browse Code »

    The "S: Orphan" in MAINTAINERS means that the maintainer in the
    "M:" field is unreachable (i.e. the email address is not working).
    (Refer to the definition of "Orphan" adopted in U-Boot
    in the log of commit 31f1b654b2f395b69faa5d0d3c1eb0803923bd3b,
    "boards.cfg: move boards with invalid emails to Orphan")

    For patch files adding global changes, scripts/get_maintainer.pl
    adds bunch of such invalid email addresses, which results in
    tons of annoying bounce emails.

    This commit can be reproduced by the following command:

    find . -name MAINTAINERS | xargs sed -i -e '
    /^M:[[:blank:]]/ {
    N
    /S:[[:blank:]]Orphan/s/^/#/
    }
    '

    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

  • 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/.

    U-Boot uses the 'mkimage' tool to produce various image types,
    not only uImage image type. Rename the invocation name from

    The following command was used to do the replacement:

    This commit refactors cleaning targets such as
    clean, clobber, mrpropper, distclean
    with scripts/Makefile.clean.

    By using scripts/Makefile.clean, we can recursively descend
    into subdirectories and delete generated files there.

    We do not need add a big list of generated files
    to the "clean" target.

  • 9e4140329   kbuild: change out-of-tree build ... Browse Code »
    43

    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.

    The SPDX License List version 1.19 now contains an official entry for
    the IBM-pibs license. However, instead of our suggestion "ibm-pibs",
    the SPDX License List uses "IBM-pibs", with the following rationale:
    "The reason being that all other SPDX License List short identifiers
    tend towards using capital letters unless spelling a word. I'd prefer
    to be consistent to this end".

    Change the license IDs to use the official name.

    This commit adapts the files that were derived from PIBS (PowerPC
    Initialization and Boot Software) codeto using SPDX License
    Identifiers.

    So far, SPDX has not assigned an official License ID for the PIBS
    license yet, so this should be considered preliminary.

    Note that the following files contained incorrect license information:

    arch/powerpc/cpu/ppc4xx/4xx_uart.c
    arch/powerpc/cpu/ppc4xx/start.S
    arch/powerpc/include/asm/ppc440.h

    These files included, in addition to the GPL-2.0 / ibm-pibs dual
    license as inherited from PIBS, a GPL-2.0+ license header which was
    obviously incorrect. This has been removed.

    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.

    PowerPC.

  • 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.

  • cdb749778   Rename getenv_r() into getenv_f() ... Browse Code »

    While running from flash, i. e. before relocation, we have only a
    limited C runtime environment without writable data segment. In this
    phase, some configurations (for example with environment in EEPROM)
    must not use the normal getenv(), but a special function. This
    function had been called getenv_r(), with the idea that the "_r"
    suffix would mean the same as in the _r_eentrant versions of some of
    the C library functions (for example getdate vs. getdate_r, getgrent
    vs. getgrent_r, etc.).

    Unfortunately this was a misleading name, as in U-Boot the "_r"
    generally means "running from RAM", i. e. _after_ relocation.

    To avoid confusion, rename into getenv_f() [as "running from flash"]
