* Make Ethernet autonegotiation on INCA-IP work for all clock rates;

Browse Source 
allow selection of clock frequency as "make" target

* Implement memory autosizing code for IceCube boards

* Configure network port on INCA-IP for autonegotiation

* Fix overflow problem in network timeout code

* Patch by Richard Woodruff, 8 Aug 2003:
  Allow crc32 to be used at address 0x000 (crc32_no_comp, too).

go 0xb0000000 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.
