[PATCH] avr32 architecture
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.

134 | * address to a memory address. | ||
135 | * | ||
136 | * Note that we prevent GCC re-ordering or caching values in expressions | ||
137 | * by introducing sequence points into the in*() definitions. Note that | ||
138 | * __raw_* do not guarantee this behaviour. | ||
139 | * | ||

22 | * | ||
23 | * upage: 1 page consisting of a user struct that tells gdb | ||
24 | * what is present in the file. Directly after this is a | ||
25 | * copy of the task_struct, which is currently not used by gdb, | ||

28 | * only one page long. | ||
29 | * data: The data segment follows next. We use current->end_text to | ||

31 | * that may have been sbrk'ed. No attempt is made to determine if a | ||

33 | * the entire range. All of the addresses are rounded in such a way | ||
34 | * that an integral number of pages is written. | ||
