Added code for reading and writing Mac addresses to/from ID EEPROM(0x57). With attached patch, we can use command "mac/mac read/mac save/" to read and write EEPROM under u-boot prompt. U-boot will calculate the checksum of EEPROM while bootup, if it is right, then u-boot will check whether the mac address of eTSEC0/1/2/3 is availalbe (non-zero). If there is mac address availabe in EEPROM, u-boot will use it, otherewise, u-boot will use the mac address defined in MPC8641HPCN.h.

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.

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. diff --git a/drivers/Makefile b/drivers/Makefile index 5a7ab71..7628f56 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -27,7 +27,7 @@ include $(TOPDIR)/config.mk LIB = $(obj)libdrivers.a -COBJS = 3c589.o 5701rls.o ali512x.o \ +COBJS = 3c589.o 5701rls.o ali512x.o atmel_usart.o \ bcm570x.o bcm570x_autoneg.o cfb_console.o cfi_flash.o \ cs8900.o ct69000.o dataflash.o dc2114x.o dm9000x.o \ e1000.o eepro100.o \ diff --git a/drivers/atmel_usart.c b/drivers/atmel_usart.c new file mode 100644 index 0000000..41c3768 --- /dev/null +++ b/drivers/atmel_usart.c @@ -0,0 +1,88 @@ +/* + * Copyright (C) 2004-2006 Atmel Corporation + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

14:42:37 +0200 Subject: 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.
