2007-10-24AVR32: Fix sg_page breakageHaavard Skinnemoen
The latest sg changes introduce the following build errors on AVR32: include/asm/dma-mapping.h: In function ‘dma_map_sg’: include/asm/dma-mapping.h:220: error: implicit declaration of function ‘sg_page’ include/asm/dma-mapping.h:220: error: invalid operands to binary - include/asm/dma-mapping.h:221: error: implicit declaration of function ‘sg_virt’ include/asm/dma-mapping.h:221: warning: assignment makes pointer from integer without a cast include/asm/dma-mapping.h: In function ‘dma_sync_sg_for_device’: include/asm/dma-mapping.h:330: warning: passing argument 2 of ‘dma_cache_sync’ makes pointer from integer without a cast Fix it by including the correct header file, i.e. linux/scatterlist.h instead of asm/scatterlist.h.

2007-10-11[AVR32] Make dma_sync_*_for_cpu no-opsHaavard Skinnemoen
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. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-03-07avr32: dma-mapping.hGary Zambrano
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.

2007-02-09[AVR32] Implement dma_mapping_error()Haavard Skinnemoen
dma_map_single() never fails, so dma_mapping_error() simply returns 0. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2006-12-08[AVR32] Pass dev parameter to dma_cache_sync()Haavard Skinnemoen

2006-12-07[PATCH] Pass struct dev pointer to dma_cache_sync()Ralf Baechle
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.

2006-12-07[PATCH] Add struct dev pointer to dma_is_consistent()Ralf Baechle
dma_is_consistent() 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_is_consistent to take a struct device pointer as first argument and fix the sole caller to pass it.

2006-09-26[PATCH] avr32 architectureHaavard Skinnemoen
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.
