  • Remove the now empty arch_reset() from all the mach/system.h includes,
    and remove its callsite. Remove arm_machine_restart() as this function
    no longer does anything useful.

    For samsung platforms, remove the include of mach/system-reset.h and
    plat/system-reset.h from their respective mach/system.h headers as these
    just define their arch_reset functions. As a result, the s3c2410 and
    plat-samsung system-reset.h files are no longer referenced, so remove
    these files entirely.

  • Boards used to specify zreladdr in their Makefile.boot with
    zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
    This patch changes this to zreladdr-y += x, so that we end
    up with multiple words in zreladdr in such a case. We can
    detect this later and complain if necessary.

  • Some platforms (like OMAP not to name it) are doing rather complicated
    hacks just to determine the base UART address to use. Let's give their
    addruart macro some slack by providing an extra work register which will
    allow for much needed cleanups.

    This is basically a no-op as this commit is only adding the extra argument
    to the macro but no one is using it yet.

  • Annotate the low level hardware locks which must not be preempted.

    In mainline this change documents the low level nature of
    the lock - otherwise there's no functional difference. Lockdep

  • Aside of the usual motivation for constification, this function has a
    history of being abused a hook for interrupt and other fixups so I turned
    this function const ages ago in the MIPS code but it should be done
    treewide.

    Due to function pointer passing in varous places a few other functions
    had to be constified as well.

    The default values for i/o and mem are 0x1000 and 0x01000000, respectively.

  • Rather than each platform providing its own function to adjust the
    zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this
    adjustment. This ensures that the actual DMA zone size and the
    ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with
    each other, and moves this complexity out of the platform code.

  • The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is

  • Commit 7c63984b86 (ARM: do not define VMALLOC_END relative to PAGE_OFFSET)
    changed VMALLOC_END to be an explicit value. Before this, it was
    relative to PAGE_OFFSET and therefore converted to unsigned long
    as PAGE_OFFSET is an unsigned long. This introduced the following
    build warning. Fix this by changing the explicit defines of
    VMALLOC_END to be unsigned long.

  • Since we're now using addruart to establish the debug mapping, we can
    remove the io_pg_offst and phys_io members of struct machine_desc.

    The various declarations were removed using the following script:

    grep -rl MACHINE_START arch/arm | xargs \
    sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

  • Rather than checking the MMU status in every instance of addruart, do it
    once in kernel/debug.S, and change the existing addruart macros to
    return both physical and virtual addresses. The main debug code can then
    select the appropriate address to use.

    This will also allow us to retreive the address of a uart for the MMU
    state that we're not current in.

  • VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
    vary depending on the selected user:kernel memory split mode through
    CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to
    accommodate more directly addressed RAM by the kernel below the vmalloc
    area, and having VMALLOC_END move along PAGE_OFFSET is rather against
    the very reason why PAGE_OFFSET can be moved in the first place.

  • 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.

  • Rather than having the central DMA multiplexer call the architecture
    specific DMA initialization function, have each architecture DMA
    initialization function use core_initcall(), and register each DMA
    channel separately with the multiplexer.

    This removes the array of dma structures in the central multiplexer,
    replacing it with an array of pointers instead; this is more flexible
    since it allows the drivers to wrap the DMA structure (eventually
    allowing us to transition non-ISA DMA drivers away.)
