    Move the SEAD-3 device-tree to arch/mips/boot/dts/ and update the
    Makefiles accordingly. Since SEAD-3 requires the device-tree to be
    built into the kernel, select BUILTIN_DTB when building for SEAD-3.

  • bfb7971c3   MIPS: SEAD3: Introduce the use of the managed version of kzalloc ... Browse Code »

    This patch moves data allocated using kzalloc to managed data allocated
    using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
    functions. Also, the now unnecessary labels out_mem and out are done
    away with. The error handling code is moved under if and return 0 is now
    at the end of the function.

    The following Coccinelle semantic patch was used for making the change:

    @platform@
    identifier p, probefn, removefn;
    @@
    struct platform_driver p = {
    .probe = probefn,
    .remove = removefn,

  • f698a3b58   MIPS: SEAD3: Don't use module_init in non-modular sead3-mtd.c code ... Browse Code »

    The sead3-mtd.o is built for obj-y -- and hence this code is always
    present. It will never be modular, so using module_init as an alias
    for __initcall can be somewhat misleading.

    Fix this up now, so that we can relocate module_init from
    init.h into module.h in the future. If we don't do this, we'd
    have to add module.h to obviously non-modular code, and that
    would be a worse thing.

    Note that direct use of __initcall is discouraged, vs. one
    of the priority categorized subgroups. As __initcall gets
    mapped onto device_initcall, our use of device_initcall
    directly in this change means that the runtime impact is
    zero -- it will remain at level 6 in initcall ordering.

    We also fix a missing semicolon, which this change uncovers.

    None of these files are actually using any __init type directives
    and hence don't need to include . Most are just a
    left over from __devinit and __cpuinit removal, or simply due to
    code getting copied from one driver to the next.

    The defaults are not always applicable and it makes it hard for the bootloader
    to override them. By removing it we give the bootloader full control over what
    command line parameters to pass.

    Without this change we will need to modify the built-in dtb to add bootloader
    cmd line parameters or do some work to append them after we unflatten the device
    tree.

    Sead3 is a development board, that's why we want to be able to change boot
    parameters on the fly from the bootloader.

  • 078a55fc8   MIPS: Delete __cpuinit/__CPUINIT usage from MIPS code ... Browse Code »
    13

    commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.

    The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    Note that some harmless section mismatch warnings may result, since
    notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
    and are flagged as __cpuinit -- so if we remove the __cpuinit from
    the arch specific callers, we will also get section mismatch warnings.
    As an intermediate step, we intend to turn the linux/init.h cpuinit
    related content into no-ops as early as possible, since that will get
    rid of these warnings. In any case, they are temporary and harmless.

    Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
    from asm files. MIPS is interesting in this respect, because there
    are also uasm users hiding behind their own renamed versions of the
    __cpuinit macros.

    the SEAD-3 can actually perform a soft reset instead of causing an

  • 28eb0e466   MIPS: drivers: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    and __devexit from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.
