The following 6 patches contain several fixes and cleanups for
the DM9000A network controller. It turned out that the U-boot DM9000 driver
was not working with this particular version of the DM9000 series.

At low speeds (10MBit) it was sometimes capable of getting a peer-2-peer
connection, but 100MBit did not work at all, also connecting the board to a
corporate network did not work at any speed.

Looking deeper at the code it turned out that many things where done
different than recommended in the Application Notes and Programming Guides
for these controllers. Doing the things as recommended solved the 
problems with the DM9000A.

The complete series has been tested with the Atmel AT91SAM9261-EK, and
a custom board, with the DM9000[A|E|EP] controllers.
