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 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
