Hi,
This is what i am getting from u-boot print messages :

This seems to me it is a old board from GDATECH . Data sheet not available 
for this.

Can you quickly check if you have the right phy id written in your 
platform file for your board?

                 Hi, 

                 Downloaded 2.6.16.26 and booted up and got this : 

                 / # ifconfig eth0 172.28.8.254 up 
                 [   34.034596] 0:00 not found

PHY 
                  such device 
                 SIOCSIFFLAGS: No such device 

                 I had enabled all the PHY devices in .config and also 
tried only with Marvell phy enabled.

                 It looks like your 2.6.12 kernel isn't handling the PHY 
correctly. 
                 I'd recommend upgrading to something newer which has the 
phylib 
                 (can't remember which 2.6 that went into).
