  • dd5e1339e   avr32: Hammerhead board support ... Browse Code »

    The Hammerhead platform is built around a AVR32 32-bit microcontroller
    from Atmel. It offers versatile peripherals, such as ethernet, usb
    device, usb host etc.

    The board also incooperates a power supply and is a Power over Ethernet
    (PoE) Powered Device (PD).

    Additonally, a Cyclone III FPGA from Altera is integrated on the board.
    The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
    DDR2 SDRAM interfaces, which will cover even the most exceptional need
    of memory bandwidth. Together with the onboard video decoder the board
    is ready for video processing.

    This patch does include the basic support for the fpga device driver,
    but not the device driver itself.

  • 9d0412680   [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories ... Browse Code »

    Now that Linux includes support for the Atmel AT91SAM9260 and
    AT91SAM9261 processors in addition to the original Atmel AT91RM9200
    (with support for more AT91 processors pending), the "mach-at91rm9200"
    and "arch-at91rm9200" directories should be renamed to indicate their
    more generic nature.

    The following git commands should be run BEFORE applying this patch:
    git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
    git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91

  • 5f97f7f94   [PATCH] avr32 architecture ... Browse Code »

    This adds support for the Atmel AVR32 architecture as well as the AT32AP7000
    CPU and the AT32STK1000 development board.

    AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for
    cost-sensitive embedded applications, with particular emphasis on low power
    consumption and high code density. The AVR32 architecture is not binary
    compatible with earlier 8-bit AVR architectures.

    The AVR32 architecture, including the instruction set, is described by the
    AVR32 Architecture Manual, available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf

    The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It
    features a 7-stage pipeline, 16KB instruction and data caches and a full
    Memory Management Unit. It also comes with a large set of integrated
    peripherals, many of which are shared with the AT91 ARM-based controllers from
    Atmel.

    Full data sheet is available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf

    while the CPU core implementation including caches and MMU is documented by
    the AVR32 AP Technical Reference, available from

    http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf

    Information about the AT32STK1000 development board can be found at

    http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918

    including a BSP CD image with an earlier version of this patch, development
    tools (binaries and source/patches) and a root filesystem image suitable for
    booting from SD card.

    Alternatively, there's a preliminary "getting started" guide available at
    http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links
    to the sources and patches you will need in order to set up a cross-compiling
    environment for avr32-linux.

    This patch, as well as the other patches included with the BSP and the
    toolchain patches, is actively supported by Atmel Corporation.
