  • f88b8979d   ARM: restart: remove the now empty arch_reset() ... Browse Code »

    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.

    Hook these platforms restart code into the new restart hook rather
    than using arch_reset().

  • 639da5ee3   ARM: add an extra temp register to the low level debugging addruart macro ... Browse Code »

    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.

  • 2fb3ec5c9   ARM: Replace platform definition of ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS ... Browse Code »

    The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is
    the physical/bus address, the other is the virtual address. Both need
    to be kept in step, so rather than having platforms define both, allow
    them to define a single macro which sets both of these macros
    appropraitely.

  • 963fec4e0   ARM: 6484/1: fix compile warning in mm/init.c ... Browse Code »

    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.

  • 0ea129300   arm: return both physical and virtual addresses from addruart ... Browse Code »

    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.

    Updated with fixes for OMAP from Jason Wang
    and Tony Lindgren , and fix for versatile express from
    Lorenzo Pieralisi .

  • 7c63984b8   ARM: do not define VMALLOC_END relative to PAGE_OFFSET ... Browse Code »

    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.

  • 4e6d488af   ARM: 5910/1: ARM: Add tmp register for addruart and loadsp ... Browse Code »

    Otherwise more complicated uart configuration won't be possible.
    We can use r1 for tmp register for both head.S and debug.S.

    NOTE: This patch depends on another patch to add the the tmp register
    into all debug-macro.S files. That can be done with:

    $ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/"
    arch/arm/*/include/*/debug-macro.S

  • 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.

  • b5ee90025   [ARM] remove a common set of __virt_to_bus definitions ... Browse Code »

    Let's provide an overridable default instead of having every machine
    class define __virt_to_bus and __bus_to_virt to the same thing. What
    most platforms are using is bus_addr == phys_addr so such is the default.

    One exception is ebsa110 which has no DMA what so ever, so the actual
    definition is not important except only for proper compilation. Also
    added a comment about the special footbridge bus translation.

    Let's also remove comments alluding to set_dma_addr which is not
    (and should not) be commonly used.
