  • 0536bdf33   ARM: move iotable mappings within the vmalloc region ... Browse Code »
    86

    In order to remove the build time variation between different SOCs with
    regards to VMALLOC_END, the iotable mappings are now allocated inside
    the vmalloc region. This allows for VMALLOC_END to be identical across
    all machines.

    The value for VMALLOC_END is now set to 0xff000000 which is right where
    the consistent DMA area starts.

    To accommodate all static mappings on machines with possible highmem usage,
    the default vmalloc area size is changed to 240 MB so that VMALLOC_START
    is no higher than 0xf0000000 by default.

  • 540b57387   ARM: 6999/1: head, zImage: Always Enter the kernel in ARM state ... Browse Code »

    Currently, the documented kernel entry requirements are not
    explicit about whether the kernel should be entered in ARM or
    Thumb, leading to an ambiguitity about how to enter Thumb-2
    kernels. As a result, the kernel is reliant on the zImage
    decompressor to enter the kernel proper in the correct instruction
    set state.

    This patch changes the boot entry protocol for head.S and Image to
    be the same as for zImage: in all cases, the kernel is now entered
    in ARM.

    Documentation/arm/Booting is updated to reflect this new policy.

    A different rule will be needed for Cortex-M class CPUs as and when
    support for those lands in mainline, since these CPUs don't support
    the ARM instruction set at all: a note is added to the effect that
    the kernel must be entered in Thumb on such systems.

    So out it goes as well.

    The PORT_S3C2400 definition in include/linux/serial_core.h is left there
    to prevent a reuse of the same number for another port type.

  • 090ab3ff8   ARM: 6886/1: mmc, Add zboot from eSD support for SuperH Mobile ARM ... Browse Code »

    This allows a ROM-able zImage to be written to eSD and for SuperH Mobile
    ARM to boot directly from the SDHI hardware block.

    This is achieved by the MaskROM loading the first portion of the image into
    MERAM and then jumping to it. This portion contains loader code which
    copies the entire image to SDRAM and jumps to it. From there the zImage
    boot code proceeds as normal, uncompressing the image into its final
    location and then jumping to it.

    Some user space applications are designed around the ability to perform
    atomic operations on 64 bit values. Since this is natively possible
    only with ARMv6k and above, let's provide a new kuser helper to perform
    the operation with kernel supervision on pre ARMv6k hardware.

    This allows a ROM-able zImage to be written to MMC and
    for SuperH Mobile ARM to boot directly from the MMCIF
    hardware block.

    This is achieved by the MaskROM loading the first portion
    of the image into MERAM and then jumping to it. This portion

    Russell, please consider merging this for 2.6.38.

    This patch depends on:
    * "mmc, sh: Move MMCIF_PROGRESS_* into sh_mmcif.h"
    which will be merged though Paul Mundt's rmobile sh-2.6.
    The absence of this patch will break the build if
    the (new) CONFIG_ZBOOT_ROM_MMCIF option is set.
    There are no subtle side-effects.

    v2:
    Addressed comments by Magnus Damm
    * Fix copyright in vrl4.c
    * Fix use of #define CONFIG_ZBOOT_ROM_MMCIF in mmcif-sh7372.c
    * Initialise LED GPIO lines in head-ap4evb.txt instead of mmcif-sh7372.c
    as this is considered board-specific.

    v3:
    Addressed comments made in person by Magnus Damm
    * Move mmcif_loader to be earlier in the image and
    reduce the number of blocks of boot program loaded by the MaskRom
    from 40 to 8 accordingly.
    * Move LED GPIO initialisation into mmcif_progress_init
    - This leaves the partner jet script unbloated
    Other
    * inline mmcif_update_progress so it is a static inline in a header file

    v4:
    * Use htole16() and htole32() in v4rl.c to ensure
    that the output is little endian

    v5:
    Addressed comments by Russell King
    * Simplify assembly code
    * Jump to code rather than an address

  • 64d2dc384   ARM: 6396/1: Add SWP/SWPB emulation for ARMv7 processors ... Browse Code »

    The SWP instruction was deprecated in the ARMv6 architecture,
    superseded by the LDREX/STREX family of instructions for
    load-linked/store-conditional operations. The ARMv7 multiprocessing
    extensions mandate that SWP/SWPB instructions are treated as undefined
    from reset, with the ability to enable them through the System Control
    Register SW bit.

    This patch adds the alternative solution to emulate the SWP and SWPB
    instructions using LDREX/STREX sequences, and log statistics to
    /proc/cpu/swp_emulation. To correctly deal with copy-on-write, it also
    modifies cpu_v7_set_pte_ext to change the mappings to priviliged RO when
    user RO.

    Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • 1dbd30e98   ARM: 6225/1: make TCM allocation static and common for all archs ... Browse Code »

    This changes the TCM handling so that a fixed area is reserved at
    0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but
    XScale does not have TCM so the mechanisms are mutually exclusive.

    This change is needed to make TCM detection more dynamic while
    still being able to compile code into it, and is a must for the
    unified ARM goals: the current TCM allocation at different places
    in memory for each machine would be a nightmare if you want to
    compile a single image for more than one machine with TCM so it
    has to be nailed down in one place.
