Michael Haas' work to debug this by looking at the phy registers
seems to be the most promising so-far, the clk reg and axp209
registers all seem to be identical between good and bad setups.

Can you try to:

1) Stop the boot in u-boot (press a key on the serial console)
2) Bring up the network, e.g. type "dhcp" then ctrl+c when it tries
to tftp
3) Do: "mii read 1 0x11" in u-boot and record the output ?

Regards,

Hans
