  • 73feb5c09   Blackfin arch: fix bugs and unify BFIN_KERNEL_CLOCK option ... Browse Code »

    - remove duplicated code and headers
    - add option allowing arbitrary SDRAM/DDR Timing parameters.
    - mark automatically calculated timings as EXPERIMENTAL
    - fix comment header block

    Related to BUGs:
    - kernel boot up fails with CONFIG_BFIN_KERNEL_CLOCK item on.
    - kernel does not boot if re-program clocks

    [ Mike Frysinger
    - fix comment header
    - mark do_sync static
    - document the DMA shutdown
    - simplify SIC_IWR handling
    - fix ANOMALY_05000265 handling to work as intended ]

    The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia
    applications where system performance and cost are essential ingredients. The
    integration of multimedia, human interface, and connectivity peripherals combined
    with increased system bandwidth and on-chip memory provides customers a platform to
    design the most demanding applications.

    Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers
    such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will
    be submitted later.

    Please enjoy the show.

    This adds support for the Analog Devices Blackfin processor architecture, and
    currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561
    (Dual Core) devices, with a variety of development platforms including those
    avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP,
    BF561-EZKIT), and Bluetechnix! Tinyboards.

    The Blackfin architecture was jointly developed by Intel and Analog Devices
    Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in
    December of 2000. Since then ADI has put this core into its Blackfin
    processor family of devices. The Blackfin core has the advantages of a clean,
    orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC
    (Multiply/Accumulate), state-of-the-art signal processing engine and
    single-instruction, multiple-data (SIMD) multimedia capabilities into a single
    instruction-set architecture.

    The Blackfin architecture, including the instruction set, is described by the
    ADSP-BF53x/BF56x Blackfin Processor Programming Reference
    http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf

    The Blackfin processor is already supported by major releases of gcc, and
    there are binary and source rpms/tarballs for many architectures at:
    http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete
    documentation, including "getting started" guides available at:
    http://docs.blackfin.uclinux.org/ which provides links to the sources and
    patches you will need in order to set up a cross-compiling environment for
    bfin-linux-uclibc

    This patch, as well as the other patches (toolchain, distribution,
    uClibc) are actively supported by Analog Devices Inc, at:
    http://blackfin.uclinux.org/

    We have tested this on LTP, and our test plan (including pass/fails) can
    be found at:
    http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel
