  • 36c0627ba   arm: imx: wandboard: fix compile error if CONFIG_VIDEO is deactivated ... Browse Code »

    When I tried to deactivate VIDEO support for the Wandboard, it still
    tried to initialize the Framebuffer and so on. That is the reason for
    the added ifdefs. CONFIG_VIDEO is enabled in the configuration as default
    and therefore nothing changes for the default user.

    The structs mx6dl_i2c2_pad_info and mx6q_i2c2_pad_info are only available
    when CONFIG_IPUV3 are set and should not be tried to access, when that
    define is not defined.

  • dac09fc10   wandboard: Make Ethernet functional again ... Browse Code »

    Since commit ce412b79e7255770 ("drivers: net: phy: atheros: add separate
    config for AR8031") ethernet does not work on mx6sabresd.

    This commit correctly assigns ar8031_config() as the configuration
    function for AR8031 in the same way as done in the Linux kernel.

    However, on wandboard design we need some additional configuration,
    such as enabling the 125 MHz AR8031 output that needs to be done
    in the board file.

    This also aligns with the same method that the kernel performs
    the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

  • ba4e159f9   wandboard: Fix hang when going into low frequency ... Browse Code »

    A kernel hang is observed when running wandboard 3.14 kernel and
    going to the lowest operational point of cpufreq:

    # ifconfig eth0 down
    # echo 1 > /sys/class/graphics/fb0/blank

    The problem is caused by incorrect setting of the REFR field
    of register MDREF. Setting it to 4 refresh commands per refresh
    cycle fixes the hang.

    Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
    REFR fields of the MDREF register as 1 and 7, respectively for
    DDR3 and 0 and 3 for LPDDR2.

    Looking at the MDREF initialization done via DCD we see that
    boards do need to initialize these fields differently:

    board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800

    So introduce a mechanism for users to be able to configure
    REFSEL and REFR fields as needed.

    Keep all the mx6 SPL users in their current REF_SEL and REFR values,
    so no functional changes for the existing users.

  • 59a6ca54f   wandboard: Simplify the Ethernet PHY configuration ... Browse Code »

    As per the AR8031 datasheet:

    "For a reliable power on reset, suggest to keep asserting the reset
    low long enough (10ms) to ensure the clock is stable and clock-to-reset
    1ms requirement is satisfied."

    So do as suggested and also add a 100us delay after deasserting the
    reset line to guarantee that the PHY ID can be read correctly and the
    Atheros 8031 PHY driver can be loaded automatically.

    This results in a simpler code.

  • 0d1ea0521   wandboard: Switch to SPL support ... Browse Code »

    Currently we need to build one U-boot image for each of the wandboard
    variants: quad, dual-lite and solo.

    By switching to SPL we can support all these variants with a single binary,
    which is very convenient.

    Based on the work from Richard Hu.

    Tested kernel booting on the three boards.

    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.

    Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}

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

  • 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/.

  • 85b8c5c4b   Merge branch 'iu-boot/master' into 'u-boot-arm/master' ... Browse Code »

    Conflicts:
    arch/arm/cpu/arm926ejs/mxs/Makefile

    board/ppcag/bg0900/Makefile
    drivers/bootcount/Makefile
    include/configs/omap4_common.h
    include/configs/pdnb3.h

    Makefile conflicts are due to additions/removals of
    object files on the ARM branch vs KBuild introduction
    on the main branch. Resolution consists in adjusting
    the list of object files in the main branch version.
    This also applies to two files which are not listed
    as conflicting but had to be modified:

    board/compulab/common/Makefile
    board/udoo/Makefile

    include/configs/omap4_common.h conflicts are due to
    the OMAP4 conversion to ti_armv7_common.h on the ARM
    side, and CONFIG_SYS_HZ removal on the main side.
    Resolution is to convert as this icludes removal of
    CONFIG_SYS_HZ.

    include/configs/pdnb3.h is due to a removal on ARM side.
    Trivial resolution is to remove the file.

    Note: 'git show' will also list two files just because
    they are new:

    include/configs/am335x_igep0033.h
    include/configs/omap3_igep00x0.h

  • 7e2173cf8   imx: iomux-v3: Include PKE and PUE to pad control pull definitions ... Browse Code »

    PUE requires PKE to mean something, as do pull values with PUE, so do not
    compell users to explicitly use PKE and PUE everywhere. This is also what is
    done on Linux and what has already been done for i.MX51.

    By the way, remove some unused pad control definitions.

    There is no change of behavior.

    Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
    without PKE or PUE, which means that no pull was actually enabled in the pad.
    This might be a bug in those boards, but this patch does not change the
    behavior, so it just removes the meaningless pull value from those definitions.
