 Hi everyone!                                                                                   
                                                                                                
 I'm  porting  the  U-boot  to  my  custom board that has a MCF5485. I had the reference of the 
 MCF5485EVB.                                                                                    
 I am using for ethernet a LXT971 chip instead a Broadcom one and I am having some problems. It 
 doesn't  work  right  and I am not sure why. Through mii console commands I can read and write 
 the  register  of  the  chip, but when I use the ethernet, for example "ping", it takes a long 
 long time.                                                                                     
 I  guess  the  problem is in the mii.c file. Probably I have to add some inital configuration, 
 but I don't know what.                                                                         
                                                                                                
 Has anyone used this LXT971 on this type of Coldfire?                                          
                                                                                                
 Thanks in advance.
