Subject: [PATCH 2/7] Use -g instead of -gstabs in AFLAGS_DEBUG Patch by
Haavard Skinnemoen, 30 Aug 2006
In config.mk, -Wa,-gstabs is unconditionally appended to AFLAGS no
matter what the target's preferred debugging format is. This patch
simply replaces -gstabs with -g, so that the default debugging format
for the architecture is used.

+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.

Subject: [PATCH 4/7] Add AT32AP CPU and AT32AP7000 SoC support Patch by
Haavard Skinnemoen, 06 Sep 2006
This patch adds support for the AT32AP CPU family and the AT32AP7000
chip, which is the first chip implementing the AVR32 architecture.
The AT32AP CPU core is a high-performance implementation featuring a
7-stage pipeline, separate instruction- and data caches, and a MMU.
For more information, please see the "AVR32 AP Technical Reference":
http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf
In addition to this, the AT32AP7000 chip comes with a large set of
integrated peripherals, many of which are shared with the AT91 series
of ARM-based microcontrollers from Atmel. Full data sheet is
available here:
http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf

Subject: [PATCH 5/7] Add common serial driver for Atmel AT32 and AT91 chips
Patch by Haavard Skinnemoen, 06 Sep 2006
This is a first attempt at creating a common serial driver for Atmel
chips. For now, it supports the AT32AP7000 AVR32 chip, but it should
be possible to support AT91RM9200 and other ARM-based chips with some
minor modifications.
There's nothing fundamentally AVR32-specific in this driver, but it
does use some features which are currently only defined for the
AT32AP CPU port:
* pm_get_clock_freq: Obtain the clock frequency of a given domain
* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
For more information about these features, please see the "AT32AP
CPU" patch.

Subject: [PATCH 6/7] Add ATSTK1000 and ATSTK1002 board support Patch by
Haavard Skinnemoen, 06 Sep 2006
This patch adds support for the ATSTK1000 with the ATSTK1002 CPU
daughterboard.
ATSTK1000 is a full-featured development board for AT32AP CPUs. It
has two ethernet ports, a high quality QVGA LCD panel, a loudspeaker,
and connectors for USART, PS/2, VGA, USB, MMC/SD cards and
CompactFlash cards. For more information, please see this page:
http://www.atmel.com/dyn/products/tools.asp?family_id=682
The ATSTK1002 is a daughterboard for the ATSTK1000 supporting the
AT32AP7000 chip.
