  • 28f9a9294   ARM: 7272/1: S3C24XX: Fix build error for missing <mach/system-reset.h> ... Browse Code »

    Since the arch/arm/mach-s3c2410/include/mach/system-reset.h has
    been removed by commit f88b8979 ("ARM: restart: remove the now
    empty arch_reset()"), so the inclusion of
    should be removed at the plat-s3c24xx/cpu.c file.

    The build error happens like following:
    arch/arm/plat-s3c24xx/cpu.c:41: fatal error: mach/system-reset.h: No such file or directory

    Remove the s3c24xx restart handler, which is trying to work around
    a chip bug by keeping caches on but flushed. As we now only disable
    caches when performing a soft reboot, there doesn't need to be a
    work-around to do that.

    So out it goes as well.

    The PORT_S3C2400 definition in include/linux/serial_core.h is left there
    to prevent a reuse of the same number for another port type.

  • 812c4e40c   ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacks ... Browse Code »

    Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure
    are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker
    error when only CONFIG_CPU_S3C2442 is selected:

    arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to
    `s3c_gpio_getpull_1up'
    arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to
    `s3c_gpio_setpull_1up'

    The s3c2442 has pulldowns instead of pullups compared to the s3c2440.
    The method of controlling them is the same though.
    So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions
    to take an additional parameter deciding whether the pin has a pullup or pulldown.
    The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing
    either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN.

    Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields
    in the s3c244{0,2}_map_io function to the new pulldown helper functions.

    Based on patch from "Lars-Peter Clausen"

    of the S3C2410A from the S3C2410. This is needed for the
    CPUFREQ code to enable the extra features and update cpu

  • be093beb6   [ARM] pass reboot command line to arch_reset() ... Browse Code »

    OMAP wishes to pass state to the boot loader upon reboot in order to
    instruct it whether to wait for USB-based reflashing or not. There is
    already a facility to do this via the reboot() syscall, except we ignore
    the string passed to machine_restart().

    This patch fixes things to pass this string to arch_reset(). This means
    that we keep the reboot mode limited to telling the kernel _how_ to
    perform the reboot which should be independent of what we request the
    boot loader to do.

  • 74b265d4e   [ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3c ... Browse Code »

    We need to add plat-s3c to the build to get the headers
    that will go in here once moved from include/asm-arm so
    we may as well put some useful common s3c code in here
    to stop the errors generated form having nothing built.

    The cpu setup is now passed the cpu idcode and the table
    of supported cpus to s3c_init_cpu() to abstract the
    cpu identification out of the initial io setup.

    As well as moving the cpu initialisation code, we move the
    map of the board specific items up to the calling code as
    none of the map_io() functions actually do anything other
    than pass this to iotable_init().

    This patch does not rename any of the init functions that
    will be common to s3c24xx and any other s3c architectures
    as this can be done at a later date as it will touch all
    the board support files which use functions such as
    s3c24xx_init_clocks() and s3c24xx_init_uarts().

    Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h
    still has functions that are used by both the cpu and
    board initialisation functions. This means that each board
    has definitions specific to the cpu support included and
    the vice-versa.

  • 3c7d9c81e   [ARM] 4987/1: S3C24XX: Ensure watchdog reset initiated from cached code. ... Browse Code »

    There seems to be some problem with at-least the S3C2440 and
    bus traffic during an reset. It is unlikely, but still possible
    that the system will hang in such a way that the watchdog cannot
    get the system out of the state it is in.

    Change to making the code that calls the watchdog reset run from
    cached memory so that instruction fetches have quiesced before the
    watchdog fires.
