* avr32: Remove include/asm-avr32/arch-at32apHaavard Skinnemoen2008-08-08
| | | | | | | Since all users have been converted over to use <mach/foo.h>, there's no need for the arch-at32ap directory and associated symlink anymore. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* [AVR32] add multidrive support for pio driverMatteo Vit2007-10-11
| | | | | | | This patch add multidrive support for pio driver Signed-off-by: Matteo Vit - Dave S.r.l. <matteo.vit@dave.eu> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Introduce at32_reserve_pin()Haavard Skinnemoen2007-02-09
| | | | | | | | at32_reserve_pin() can be used for reserving portmux pins without altering their configuration. Useful for e.g. SDRAM pins where we really don't want to change the bootloader-provided configuration. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] GPIO API implementationHaavard Skinnemoen2007-02-09
| | | | | | | Arch-neutral GPIO calls for AVR32. GPIO IRQ support written by David Brownell. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Portmux API updateHaavard Skinnemoen2006-12-08
| | | | | | | Rename portmux_set_func to at32_select_periph, add at32_select_gpio and add flags parameter to specify the initial state of the pins. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [PATCH] avr32 architectureHaavard Skinnemoen2006-09-26
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.
