  • ce3de78a1   m68knommu: remove ColdFire CLOCK_DIV config option ... Browse Code »

    The reality is that you do not need the abiltity to configure the
    clock divider for ColdFire CPUs. It is a fixed ratio on any given
    ColdFire family member. It is not the same for all ColdFire parts,
    but it is always the same in a model range. So hard define the divider
    for each supported ColdFire CPU type and remove the Kconfig option.

  • 6a92e1982   m68knommu: clean up use of MBAR for DRAM registers on ColdFire start ... Browse Code »

    In some of the RAM size autodetection code on ColdFire CPU startup
    we reference DRAM registers relative to the MBAR register. Not all of
    the supported ColdFire CPUs have an MBAR, and currently this works
    because we fake an MBAR address on those registers. In an effort to
    clean this up, and eventually remove the fake MBAR setting make the
    DRAM register address definitions actually contain the MBAR (or IPSBAR
    as appropriate) value as required.

  • babc08b7e   m68knommu: move ColdFire DMA register addresses to per-cpu headers ... Browse Code »

    The base addresses of the ColdFire DMA unit registers belong with
    all the other address definitions in the per-cpu headers. The current
    definitions assume they are relative to an MBAR register. Not all
    ColdFire CPUs have an MBAR register. A clean address define can only
    be acheived in the per-cpu headers along with all the other chips
    peripheral base addresses.

  • a0ba4332a   m68knommu: remove use of MBAR value for ColdFire 528x peripheral addressing ... Browse Code »

    The ColdFire 528x family of CPUs does not have an MBAR register, so don't
    define its peripheral addresses relative to one. Its internal peripherals
    are relative to the IPSBAR register, so make sure to use that.

  • f317c71a2   m68knommu: move ColdFire PIT timer base addresses ... Browse Code »

    The PIT hardware timer module used in some ColdFire CPU's is not always
    addressed relative to an IPSBAR register. Parts like the ColdFire 5207 and
    5208 have fixed peripheral addresses. So lets not define the register
    addresses of the PIT relative to an IPSBAR definition. Move the base
    address definitions into the per-part headers. This is a lot more consistent
    since all the other peripheral base addresses are defined in the per-part
    header files already.

  • 254eef746   m68knommu: remove kludge seting of MCF_IPSBAR for ColdFire 54xx ... Browse Code »

    The ColdFire 54xx family shares the same interrupt controller used
    on the 523x, 527x and 528x ColdFire parts, but it isn't offset
    relative to the IPSBAR register. The 54xx doesn't have an IPSBAR
    register.

    By including the base address of the peripheral registers in the register
    definitions (MCFICM_INTC0 and MCFICM_INTC1 in this case) we can avoid
    having to define a fake IPSBAR for the 54xx. And this makes the register
    address definitions of these more consistent, the majority of the other
    register address defines include the peripheral base address already.

  • 91d604172   m68knommu: Coldfire QSPI platform support ... Browse Code »

    Since Grant has added the coldfire-qspi driver to next-spi, here is the
    platform support for the parts that have qspi hardware. This sets up
    gpio to do the spi chip select using the default chip select pins; it should
    be trivial for boards that require different or additional spi chip selects to
    use other gpios as needed.

  • 49148020b   m68k,m68knommu: merge header files ... Browse Code »

    Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

    The majority of this patch was the result of the
    script that is included in the changelog below.

    The script was originally written by Arnd Bergman and
    exten by me to cover a few more files.

    When the header files differed the script uses the following:

    The original m68k file is named _mm.h [mm for memory manager]
    The m68knommu file is named _no.h [no for no memory manager]

    The files uses the following include guard:

    This include gaurd works as the m68knommu toolchain set
    the __uClinux__ symbol - so this should work in userspace too.

    Merging the header files for m68k and m68knommu exposes the
    (unexpected?) ABI differences thus it is easier to actually
    identify these and thus to fix them.

    The commit has been build tested with both a m68k and
    a m68knommu toolchain - with success.

    The commit has also been tested with "make headers_check"
    and this patch fixes make headers_check for m68knommu.
