  • f861f51c4   ls102xa: Fix reset hang ... Browse Code »

    Since commit 623d96e89aca6("imx: wdog: correct wcr register settings")
    issuing a 'reset' command causes the system to hang.

    Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian.

    This means that the watchdog on LS1021 has been working by accident as
    it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c.
    Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only
    revelead the endianness problem on LS102x.

    In order to fix the reset hang, introduce a reset_cpu() implementation that
    is specific for ls102x, which accesses the watchdog WCR register in big-endian
    format. All that is required to reset LS102x is to clear the SRS bit.

    This approach is a temporary workaround to avoid a regression for LS102x
    in the 2015.10 release. The proper fix is to make the watchdog driver
    endian-aware, so that it can work for i.MX, Vybrid and LS102x.

  • f532727d1   imx_watchdog: Add a header file for watchdog registers ... Browse Code »

    Create fsl_wdog.h to store the watchdog registers and bit fields.

    This can be useful when accesses to the watchdog block are made from other
    parts, such as arch/arm/ cpu code.

    We should not simple use "writew(WCR_WDE, &wdog->wcr)" to set
    wcr, since this will override bits set before reset_cpu.

    Use clrsetbits_le16 instead of writew to fix this issue.

  • 5cab87405   watchdog/imx_watchdog: do not set WCR_WDW ... Browse Code »

    with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle
    around while the watchdog is not triggered. It seems the timer makes
    progress very slowly if at all. I managed to remain 20minutes alive
    while the timeout was set to 60secs. It reboots within 60secs if I start
    a busyloop in userland (something like "while (1) { }").

    While I don't see a reason why the WDT should not be running while the
    CPU is in idle, I'm dropping this bit.

    The QorIQ LS1 family is built on Layerscape architecture,
    the industry's first software-aware, core-agnostic networking
    architecture to offer unprecedented efficiency and scale.

    Freescale LS102xA is a set of SoCs combines two ARM
    Cortex-A7 cores that have been optimized for high
    reliability and pack the highest level of integration
    available for sub-3 W embedded communications processors
    with Layerscape architecture and with a comprehensive
    enablement model focused on ease of programmability.

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

    Conflicts:
    arch/arm/cpu/arm926ejs/mxs/Makefile
    board/compulab/cm_t35/Makefile
    board/corscience/tricorder/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

  • 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.
