Perhaps, your Ethernet driver is not properly configured. Recheck these
definitions in your include/configs/tc870.h file:
#define CONFIG_NET_MULTI 1 /* the only way to get the FEC in
*/
#define FEC_ENET 1 /* eth.c needs it that way... */
#define CONFIG_FEC_ENET 1
#undef CFG_DISCOVER_PHY
#define CONFIG_MII 1
#define CONFIG_RMII 1 /* use RMII interface */
I would pay special attention to CFG_DISCOVER_PHY. Maybe the wrong
Phy is being configured?

Maybe someone with experience with Ethernet on the MPC870 can answer?
I don't have a tc870 board or an MPC870, so this is the last
time you'll hear from me on this topic.
Good luck!
