mmc: Move atmel_mci driver into drivers/mmc

2008-07-09T22:05:52+00:00

This makes it easier to use the driver on other platforms.

avr32: Use CONFIG_ATMEL_MCI to select the atmel_mci driver

2008-07-09T22:04:47+00:00

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 conditionally

2008-05-27T13:27:31+00:00

Remove #ifdef CONFIG_MMC from the source file and use conditional
compilation in the Makefile instead.

avr32: Use the same entry point for reset and exception handling

2008-05-27T13:27:30+00:00

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 platform

2008-05-27T13:27:30+00:00

This makes it easier to avoid compiling certain files later.

Atmel MCI driver

2007-04-14T14:14:06+00:00

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

AVR32: Resource management rewrite

2007-04-14T13:20:27+00:00

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.

Fix "ar" flags in some Makefiles to allow for silent "make -s"

Add AT32AP CPU and AT32AP7000 SoC support

2006-10-24T12:27:35+00:00

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:
