On the bootp time out, you appear to be sending ARP packets and not getting
a response. Is your BOOTP server properly configured? To be specific, is
it configured to be 192.168.10.1? Your etherdump trace (ARP with no
response and ICMP "unreachable" error packets) implies not. Ping it to
check, preferably from your custom MPC860P board.
Are you sniffing the ethernet from a different machine than your custom
MPC860P board? You should be: otherwise you don't know if the packet
actually gets transmitted on the ethernet. This could also cause the "no
ARP response" symptoms you show.
It probably isn't significant, and could just be my ignorance, but there
also appears to be a missmatch with the MAC address used: your bootp line
shows 0:e0:4c:45:56:af but your ARP request appears to be using
0:e0:4c:3b:f6:ca.
