  • 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.

  • We only need to set the system up for a soft-restart if we're going to
    be doing a soft-restart. Provide a new function (soft_restart()) which
    does the setup and final call for this, and make platforms use it.
    Eliminate the call to setup_restart() from the default handler.

    This means that platforms arch_reset() function is no longer called with
    the page tables prepared for a soft-restart, and caches will still be
    enabled.

  • 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.

  • To be able to relocate the .bss section at run time independently from
    the rest of the code, we must make sure that no GOTOFF relocations are
    used with .bss symbols. This usually means that no global variables can
    be marked static unless they're also const.

    Let's remove the static qualifier from current offenders, or turn them
    into const variables when possible. Next commit will ensure the build
    fails if one of those is reintroduced due to otherwise enforced coding
    standards for the kernel.

  • 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.

  • 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 .

  • 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.

  • 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

  • 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.

  • The hardware supports transfers up to a page boundary per buffer.
    Currently, we work around that in the DMA code by splitting each
    buffer up as we run through the scatterlist. Avoid this by telling
    the block layers about the hardware restriction.

    Eventually, this will allow us to phase out the splitting code,
    but not until the old IDE layer allows us to control the value it
    gives to blk_queue_segment_boundary().

  • 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.
