Well, don't be mad at me first. The question may bring out another
round of arguments whether it's a bug related to uboot or linux EMAC
driver. Wolfgang makes it very clear that this is a bug in linux
ethernet driver. And I agree with him. This argument happened before
and I just forgot what specific ethernet driver was in the argument.

So the EMAC driver does expect a boot loader (the firmware you
mentioned here) to set something for it. Then I think I need to fix it
in this driver instead of in uboot.
