go 0xb0000000
Ethernet autonegotiation needs some time to complete. Instead of
delaying the boot process in all cases, we just start the
autonegotiation process when U-Boot comes up and that is all. Most
likely, it will complete by the time the network transfer is
attempted for the first time. In the worst case, if a transfer is
attempted before the autonegotiation is complete, just a single
packet would be lost resulting in a single timeout error, and then
the transfer would proceed normally. So the time that we would have
lost unconditionally waiting for the autonegotiation to complete, we
have to wait only if the file transfer is started immediately after
reset. We've verified that this works for all the clock
configurations.
