  • e895a4b06   fdt: Allow ft_board_setup() to report failure ... Browse Code »

    This function can fail if the device tree runs out of space. Rather than
    silently booting with an incomplete device tree, allow the failure to be
    detected.

    Unfortunately this involves changing a lot of places in the code. I have
    not changed behvaiour to return an error where one is not currently
    returned, to avoid unexpected breakage.

    Eventually it would be nice to allow boards to register functions to be
    called to update the device tree. This would avoid all the many functions
    to do this. However it's not clear yet if this should be done using driver
    model or with a linker list. This work is left for later.

  • 535aad29f   MAINTAINERS: comment out blank M: field ... Browse Code »

    Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4
    (patman: RunPipe() should not pipe stdout/stderr unless asked),
    Patman spits lots of "Invalid MAINTAINERS address: '-'"
    error messages for patches with global changes.
    It takes too long for Patman to process them.

    Anyway, "M: -" does not carry any important information.
    Rather, it is just like a place holder in case of assigning
    a new board maintainer. Let's comment out.

    This commit can be reproduced by the following command:

    find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

  • 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//
    }
    '

  • 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/.

  • 9d0456822   powerpc/mpc85xx: Check return value of find_tlb_idx ... Browse Code »

    find_tlb_idx() is called in board_early_init_r() on multiple boards.
    The return value is not checked before being used to disable a TLB.
    In normal case the return value wouldn't be -1. In case of a mis-
    configuration during porting to a new board, checking the return value
    may be helpful to reveal some user errors.

  • 997399fa4   powerpc: Fix CamelCase checkpatch warnings ... Browse Code »

    85xx, 86xx PowerPC folders have code variables with CamelCase naming conventions.
    because of this code checkpatch script generates "WARNING: Avoid CamelCase".

    Convert variables name to normal naming convention and modify board, driver
    files with updated the new structure.

    JEDEC spec requires the clocks to be stable before deasserting reset
    signal for RDIMMs. Clocks start when any chip select is enabled and
    clock control register is set. This patch also adds the interface to
    toggle memory reset signal if needed by the boards.
