  • 716a3dc20   ARM: Add arm_memblock_steal() to allocate memory away from the kernel ... Browse Code »
    43

    Several platforms are now using the memblock_alloc+memblock_free+
    memblock_remove trick to obtain memory which won't be mapped in the
    kernel's page tables. Most platforms do this (correctly) in the
    ->reserve callback. However, OMAP has started to call these functions
    outside of this callback, and this is extremely unsafe - memory will
    not be unmapped, and could well be given out after memblock is no
    longer responsible for its management.

    So, provide arm_memblock_steal() to perform this function, and ensure
    that it panic()s if it is used inappropriately. Convert everyone
    over, including OMAP.

    As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot
    with this change. Mark this option as BROKEN and make it depend on
    BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix
    errata i688 with MPU interconnect barriers.) reverted until such
    time it can be fixed correctly.

  • b78d8e59a   gpio/mxc: Change gpio-mxc into an upstanding gpio driver ... Browse Code »

    The patch makes necessary changes on gpio-mxc as below to turn it
    into an upstanding gpio driver.

    * Add a list to save all mx2 ports references, so that
    mx2_gpio_irq_handler can walk through all interrupt status
    registers

    * Use readl/writel to replace mach-specific accessors
    __raw_readl/__raw_writel

    * Change mxc_gpio_init into mxc_gpio_probe function

    * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
    be public at all, and also make some other cleanup on
    plat-mxc/include/mach/gpio.h at the same time

    And the patch then migrates mach-imx and mach-mx5 to the updated
    driver by adding corresponding platform devices.
