  • 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.

  • 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.

    As Al did for Versatile in 2ad4f86b60b649fd7428265c08d73a3bd360c81b,
    add a typesafe __io implementation for platforms to use. Convert
    platforms to use this new simple typesafe implementation.

  • 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.

  • cb90d681a   [ARM] 2980/1: Fix L7200 core.c compile ... Browse Code »

    Patch from Deepak Saxena

    This patch fixes L7200 so that it builds in 2.6.latest. I do not
    have the hardware so don't know if it actually still works, but
    the changes are fairly trivial. I am not even sure if anyone
    still maintains, uses, or cares about this machine type.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
