It may be desirable (at least as an option) to always perform the PHY
reset (just the reset, i. e. the hardware initialization) without
waiting for a link to come up.  Link negotiation could then happen "in
background", while other parts of U-Boot initialization are running.
When U-Boot actually performs a network command, it ill not have to
wait as long as in the case when we start resetting the PHY here.

I am well aware that this is not in line with the principle of
initializing the hardware only if needed, but short boot times are a
common requirement, so one might consider such an option.  [I would
not recommend (or accept) this as the default case.]

Best regards,

Wolfgang Denk
