I added this code to the uec.c file:
int i;
for(i=0;i<20;i++)
printf("PHY value %d is %x\n", i, phy_read(uec->mii_info, i));
and got this to the prompt..
PHY value 0 is 0
PHY value 1 is 0
PHY value 2 is 0
PHY value 3 is 0
PHY value 4 is 0
PHY value 5 is 0
PHY value 6 is 0
PHY value 7 is 0
PHY value 8 is 0
PHY value 9 is 0
PHY value 10 is 0
PHY value 11 is 0
PHY value 12 is 0
PHY value 13 is 0
PHY value 14 is 0
PHY value 15 is 0
PHY value 16 is 0
PHY value 17 is 0
PHY value 18 is 0
PHY value 19 is 0
