+Subject: [PATCH] AVR32 architecture support
+
+This patch adds common infrastructure code for the Atmel AVR32
+architecture.
+
+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
+
+A GNU toolchain with support for AVR32 is included with the ATSTK1000
+BSP, which can be downloaded as an ISO image from
+
+http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918
+
+Alternatively, you can build it yourself by following the
+Getting Started guide at avr32linux.org, which also provides links
+to the necessary sources and patches you need to download:
+
+http://avr32linux.org/twiki/bin/view/Main/GettingStarted
+
+The AVR32 ports of u-boot, the Linux kernel, the GNU toolchain and
+other associated software are actively supported by Atmel Corporation.
