  • 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().

    In doing so, we split out the ixdp2351 restart code into its own
    platform file.

  • 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.

  • c9d95fbe5   ARM: convert PCI defines to variables ... Browse Code »

    Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
    multi-platform builds. This also removes the requirement for a platform to
    have a mach/hardware.h.

    The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
    Per Arnd Bergmann, other values are likely to be incorrect, but this commit
    does not try to address that issue.

  • 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 .

  • 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.

  • dcea83adc   [ARM] Hide ISA DMA API when ISA_DMA_API is unset ... Browse Code »

    When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
    so there's no point in publishing the prototypes via asm/dma.h, nor
    including the machine dependent parts of that API.

    This allows us to remove a lot of mach/dma.h files which don't contain
    any useful code. Unfortunately though, some platforms put their own
    private non-ISA definitions into mach/dma.h, so we leave these behind
    and fix the appropriate #include statments.

  • 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.
