  • b5a8e7362   [AVR32] Make dma_sync_*_for_cpu no-ops ... Browse Code »

    I don't think the dma_sync_*_for_cpu ever did anything useful. We
    flush the relevant cache lines when mapping the buffer or when calling
    dma_sync_*_for_device(), and the CPU isn't allowed to touch the buffer
    after that.

    In other words, if these functions actually have anything to flush
    from the caches, we're already in trouble.

    Added dma_sync_single_range_for_cpu/device to dma-mapping.h in asm-avr32 to
    call dma_sync_single_for_cpu/device. This patch enables b44 to compile on
    systems with these cpus. This patch was created with the assumption that
    another method of dma_sync_single_range_for_cpu/device does not exist on these
    architectures.

    Pass struct dev pointer to dma_cache_sync()

    dma_cache_sync() is ill-designed in that it does not have a struct device
    pointer argument which makes proper support for systems that consist of a
    mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
    to take a struct device pointer as first argument and fix all its callers
    to pass it.

  • 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.
