+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.

+
+ $ make MPC8641HPCN_config

+
+3. Flash U-Boot
+---------------
+The flash range 0xFF800000 to 0xFFFFFFFF can be divided into 2 halves.
+It is possible to use either half to boot using u-boot. Switch 5 bit 2
+is used for this purpose.
+
+0xFF800000 to 0xFFBFFFFF - 4MB
+0xFFC00000 to 0xFFFFFFFF - 4MB
+When this bit is 0, U-Boot is at 0xFFF00000.
+When this bit is 1, U-Boot is at 0xFFB00000.
+
+Use the above mentioned flash commands to program the other half, and
+use switch 5, bit 2 to alternate between the halves. Note: The booting
+version of U-Boot will always be at 0xFFF00000.
+
+To Flash U-Boot into the booting bank (0xFFC00000 - 0xFFFFFFFF):
+
+ tftp 1000000 u-boot.bin
+ protect off all
+ erase fff00000 ffffffff
+ cp.b 1000000 fff00100 80000
+
+To Flash U-boot into the alternative bank (0xFF800000 - 0xFFBFFFFF):
+
+ tftp 1000000 u-boot.bin
+ erase ffb00000 ffbfffff
+ cp.b 1000000 ffb00100 80000
+
+
+4. Memory Map
