+From: Haavard Skinnemoen <hskinnemoen@atmel.com>
+
+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.
