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

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. Full data sheet is
available here:
