    Subject[PATCH -mm 1/5] Blackfin: blackfin architecture patch update
    From
    Date
    Hi folks,

    Here is the update version of blackfin-arch.patch in -mm tree.
    simply add support to utrace and it was tested on blackfin STAMP board
    as well as other following patches.

    The whole patch is located at URL:
    https://blackfin.uclinux.org/gf/download/frsrelease/39/2583/blackfin-arch.patch
    The incremental patch is located at URL:

    [PATCH] Blackfin Architecture

    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
    it’s 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
