EP405 network interface

I ended up hard-coding the interface since the 2_4_devel tree was shifting
on EP405 support quite a bit.  Some EP405 boards worked and some didn't.
Once you tell it it definitely has one (unconditionally) it sails along

I also found that booting out of flash does the same thing regardless of
the EP405 board.  I had to initialize the interface via the firmware before
the Linux driver work work.  I wasn't able to hard-code around that one.

Another point to keep in mind - the linux bootloader code will assume clock
rates for everything.  They're not always correct and that screwed up a lot
of things.  You may want to double check those.

} Did you enable the phy in the Board Control Status Register?

} Hi all,
} I cannot get the NIC working on my EP405. I used the ep405_config from
} the linuxppc_2_4_devel tree.
} This is a part of the output:
} ...
} loop: loaded (max 8 devices)
} eth0: No PHY device found.
} removing net dev
} ...
} So it seems that the kernel doesn't find the NIC (but it is there, and
} working, ep-bootloader can use it to download the image).
} Anybody an idea?
} I already checked the NIC support, and the onboard-IBM NIC support is
} enabled.
