da3854fc9f DM9000: Fixup blackfin after removing 2 resource usage
The dm9000 driver accepts either 2 or 3 resources to describe the platform
devices. The 2 resources case abuses the ioresource mechanism by passing
ioremap()ed memory through the platform device resources. This patch removes
converts boards that were using it to the 3 resources scheme.

3760f73671 i2c: Convert most new-style drivers to use module aliasing
Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

Changes:

1. The baud for spi mmc defined in board file is not used by the old
spi driver. A slower value from spi framework is used instead. In latest
bug fixing, the correct baud is use which is too high for spi MMC card.

2. SPI is enabled only after DMA is started.

3. MMC detection IRQ is set to 55.

The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia
applications where system performance and cost are essential ingredients. The
integration of multimedia, human interface, and connectivity peripherals combined
with increased system bandwidth and on-chip memory provides customers a platform to
design the most demanding applications.

Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers
such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will
be submitted later.

Please enjoy the show.

1394f03221 blackfin architecture
This adds support for the Analog Devices Blackfin processor architecture, and
currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561
(Dual Core) devices, with a variety of development platforms including those
avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP,
BF561-EZKIT), and Bluetechnix!  Tinyboards.

The Blackfin architecture was jointly developed by Intel and Analog Devices
Inc.  (ADI) as the Micro Signal Architecture (MSA) core and introduced it in
December of 2000.  Since then ADI has put this core into its Blackfin
processor family of devices.  The Blackfin core has the advantages of a clean,
orthogonal,RISC-like microprocessor instruction set.  It combines a dual-MAC
(Multiply/Accumulate), state-of-the-art signal processing engine and
single-instruction, multiple-data (SIMD) multimedia capabilities into a single
instruction-set architecture.

The Blackfin architecture, including the instruction set, is described by the
ADSP-BF53x/BF56x Blackfin Processor Programming Reference
http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf

The Blackfin processor is already supported by major releases of gcc, and
there are binary and source rpms/tarballs for many architectures at:
http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete
documentation, including "getting started" guides available at:
http://docs.blackfin.uclinux.org/ which provides links to the sources and
patches you will need in order to set up a cross-compiling environment for
bfin-linux-uclibc

This patch, as well as the other patches (toolchain, distribution,
uClibc) are actively supported by Analog Devices Inc, at:
http://blackfin.uclinux.org/

We have tested this on LTP, and our test plan (including pass/fails) can
be found at:
