This issue has been brought up once before:
http://lists.denx.de/pipermail/u-boot/2009-February/046829.html

There was some concern about adding delay to the boot process in the
case that the primary ethernet port(s) did not achieve link.

There had also been some discussion about performing PHY
auto-negotiation in parallel, but this seems like a much larger can of
worms.

I had proposed this:

Andy/Ben, any feedback on getting a patch such as Michael's or mine
merged in?

Thanks,
Peter
