minor progress with plb_temac v3.00a, EDK 8.2, & 2.6.18.1

Rimas;

Good call on the PHY address.  I thought that I was on to something when
I saw that a week or so ago; however, after I checked the datasheet on the
MARVELL 88E1111 PHY chip and its connection on the ML403 board, I
found that it is addressed to 0b00000.

It does appear that access to the mgmt registers is working, albeit not completely
as expected (see boot dump, below) with regards to the PHY ID.

The initialization process is pretty simple:

1.   Query the PHY [using  XTemac_PhyRead(...)] and see what speed it's set to:

    [    5.358347] XTemac(set_mac_speed): PHY Speed from XTemac_PhyRead() = 0M, where 2=1000M, 1=100M, and 0=10M


2.    Set the MAC to the same speed (in a switch statement):
            XTemac_SetOperatingSpeed(&lp->Emac, 10);

I suspect that the problem is with the first step as it is reporting a different speed than what the LED's on the board show.

Any thoughts?
