  • 7a6541721   mtd/ifc: Add support for IFC controller version 2.0 ... Browse Code »

    The new IFC controller version 2.0 has a different memory map page.
    Upto IFC 1.4 PAGE size is 4 KB and from IFC2.0 PAGE size is 64KB.
    This patch segregates the IFC global and runtime registers to appropriate
    PAGE sizes.

  • c4aa1937b   fsl-ifc: add missing include on ARM64 ... Browse Code »

    Need to include sched.h to fix the following compilation error
    if FSL_IFC is enabled on ARM64 machine.

    In file included from include/linux/mmzone.h:9:0,
    from include/linux/gfp.h:5,
    from include/linux/kmod.h:22,
    from include/linux/module.h:13,
    from drivers/memory/fsl_ifc.c:22:
    drivers/memory/fsl_ifc.c: In function ‘check_nand_stat’:
    include/linux/wait.h:165:35: error: ‘TASK_NORMAL’ undeclared (first use in this function)
    #define wake_up(x) __wake_up(x, TASK_NORMAL, 1, NULL)
    ^
    drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
    wake_up(&ctrl->nand_wait);
    ^
    include/linux/wait.h:165:35: note: each undeclared identifier is reported only once for each function it appears in
    #define wake_up(x) __wake_up(x, TASK_NORMAL, 1, NULL)
    ^
    drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
    wake_up(&ctrl->nand_wait);
    ^

    Analysis is as follows:
    I put some instrumental code and get the
    following .h files inclusion sequence:

    In file included from ./arch/arm64/include/asm/compat.h:25:0,
    from ./arch/arm64/include/asm/stat.h:23,
    from include/linux/stat.h:5,
    from include/linux/module.h:10,
    from drivers/memory/fsl_ifc.c:23:
    include/linux/sched.h:113:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘struct’
    struct sched_attr {
    ^

    CONFIG_COMPAT=y is enabled while 39 and 48 bit VA is selected.
    When 42 bit VA is selected, it does not enable CONFIG_COMPAT=y

    In ./arch/arm64/include/asm/stat.h:23, it has
    "#ifdef CONFIG_COMPAT"
    "#include "
    "..."
    "#endif"

    Since ./arch/arm64/include/asm/stat.h does not
    include ./arch/arm64/include/asm/compat.h,
    then it will not include include/linux/sched.h
    Hence we have to manually add "#include "
    in drivers/memory/fsl_ifc.c

  • d2ae2e20f   driver/memory:Move Freescale IFC driver to a common driver ... Browse Code »

    Freescale IFC controller has been used for mpc8xxx. It will be used
    for ARM-based SoC as well. This patch moves the driver to driver/memory
    and fix the header file includes.

    Also remove module_platform_driver() and instead call
    platform_driver_register() from subsys_initcall() to make sure this module
    has been loaded before MTD partition parsing starts.
