avr32: add generic_find_next_le_bit bit function

2008-09-19T16:21:30Z

This patch implements the generic_find_next_le_bit bit function for AVR32 architecture. This is used by EXT4 file system. Signed-off-by: Hans-Christian Egtvedt Signed-off-by: Haavard Skinnemoen

avr32: Fix wrong I/O access size in __raw_readsb

2008-06-27T13:07:50Z

__raw_readsb() should always use byte accesses, never halfword accesses, to I/O memory. Signed-off-by: Haavard Skinnemoen

read_current_timer() cleanups

2008-02-06T18:41:02Z

- All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

[AVR32] Remove last remains of libgcc

2007-02-09T14:01:59Z

Two libgcc headers were left around even though all the actual code borrowed from libgcc is gone. Delete them. Signed-off-by: Haavard Skinnemoen

[AVR32] Add missing #include to delay.c

2006-12-08T12:08:30Z

__const_udelay() needs HZ, which is defined in . Signed-off-by: Haavard Skinnemoen

[AVR32] Don't include

2006-12-08T12:06:24Z

Include instead of from a few places. Signed-off-by: Haavard Skinnemoen

AVR32: Add missing return instruction in __raw_writesb

2006-11-06T13:07:16Z

__raw_writesb ends with a conditional branch, which is obviously wrong. It should return after the last loop terminates. Signed-off-by: Haavard Skinnemoen

AVR32: Fix thinko in generic_find_next_zero_le_bit()

2006-11-06T09:43:24Z

The existing implementation of this function seems to be looking for a one although it should be looking for a zero. This causes trouble for the ext2 filesystem, which tends to report -ENOSPC without this patch. Fix this by complementing each word before scanning. Signed-off-by: Haavard Skinnemoen

[PATCH] AVR32: Implement and export __raw_{read,write}s[bwl]

2006-10-26T03:26:33Z

Implement __raw_readsb and __raw_writesb. Export __raw_reads[bwl] and __raw_writes[bwl] for use by modules. Signed-off-by: Haavard Skinnemoen Signed-off-by: Linus Torvalds

[PATCH] avr32 architecture

2006-09-26T15:48:54Z

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.
