* mmc: Move atmel_mci driver into drivers/mmcHaavard Skinnemoen2008-07-10-1/+0
| | | | | | | This makes it easier to use the driver on other platforms. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Acked-by: Jean-Chritophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* avr32: Use CONFIG_ATMEL_MCI to select the atmel_mci driverHaavard Skinnemoen2008-07-10-1/+1
| | | | | | | | | After we move the atmel_mci driver into drivers/mmc, we can't select it with CONFIG_MMC anymore. Introduce a new symbol specifically for this driver so that there's no ambiguity.

* avr32: Compile atmel_mci.o conditionallyHaavard Skinnemoen2008-05-27-1/+1
| | | | | | | Remove #ifdef CONFIG_MMC from the source file and use conditional compilation in the Makefile instead. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Use the same entry point for reset and exception handlingHaavard Skinnemoen2008-05-27-1/+0
| | | | | | | | | | | | | | Since the reset vector is always aligned to a very large boundary, we can save a couple of KB worth of alignment padding by placing the exception vectors at the same address. Deciding which one it is is easy: If we're handling an exception, the CPU is in Exception mode. If we're starting up after reset, the CPU is in Supervisor mode. So this adds a very minimal overhead to the reset path (only executed once) and the exception handling path (normally never executed at all.)

* avr32: Use new-style Makefile for the at32ap platformHaavard Skinnemoen2008-05-27-7/+14

* Atmel MCI driverHaavard Skinnemoen2007-04-14-1/+1
| | | | | | | | | | | | | | Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs. The AT91 ARM-based CPUs use basically the same hardware, so it should be possible to share this driver, but no effort has been made so far. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* AVR32: Resource management rewriteHaavard Skinnemoen2007-04-14-1/+1
| | | | | | | | | | | | | Rewrite the resource management code (i.e. I/O memory, clock gating, gpio) so it doesn't depend on any global state. This is necessary because this code is heavily used before relocation to RAM, so we can't write to any global variables. As an added bonus, this makes u-boot's memory footprint a bit smaller, although some functionality has been left out; all clocks are enabled all the time, and there's no checking for gpio line conflicts.

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.
