Fixed PHY problems

[Hammond Christian-r55079]

Thanks,

Regarding the PHY set-up in the dts once the patch has been applied, how
should it be implemented?

I had edited from...

phy1:	ethernet-phy at 01 {
		reg = <0>;
		device_type = "ethernet-phy";
		interface = <6>;
	}; 

To...

phy1:	fixed-phy at 64 {
		reg = <d#100>;
		device_type = "ethernet-phy";
		interface = <6>;
	};

When bringing up the fixed phy in ifconfig I get the following recurring
dump and prompt access is lost. Should this implementation not just
ignore the phy set-up?

~ # ifconfig eth1 10.137.32.175 netmask 255.255.255.0 up
read wrong value : mii_id 100,mii_reg 2, base d100c120
read wrong value : mii_id 100,mii_reg 3, base d100c120
eth1: PHY is Generic MII (ffffffff)

Vitaly sent me the patch, had to do some minor tweaking to make it
compile. Attaching the patch.

No, the fixed PHY is on another bus than what ucc_geth expects.
See msg from me titled "Fixed  PHY and MPC832x based boards don't work"
from about a week ago.
