The root file system is JFFS2 which i have made using mkfs.jffs2 utility which comes along with the ELDK 3.0 In the kernel code i checked that there is support for the LXT971 chip, but even after enabling all the network related funcuntionalities in the linux kernel configuration, I am either not able to ping from the board to any machine on the network, nor from the any other machine to the board. The board is able to ping itself. Can some one please throw some light why the board is not able to ping any other machine.

MPC8272 use SCC3 and MPC8270 use SCC4. Added some more clock configuration options ... I think the changes are quite generic. The driver seems to work with a 2.6.13 kernel. Only some basic tests is performed with - serial ftdi_sio to ports ttyUSB0 & ttyUSB1 - storage i.e. some kind of "no name" usb-memory - 3 1/4 floppy drive - Nokia hub. Don't you think u-boot should take care of clock setup i.e. as much as possible of all board dependent stuff ?

No, it should not. A river should not make any assumptions about the state of the hardware, but initialize everything it needs for correct operation itself.

It appears you have correctly assigned MAC and IP addresses. The problem does appear to be at the hardware level, because the ethernet interface is not doing anything at all. My guess would be that the driver is not configured for the correct pins. You mentioned that you are using custom hardware, so look, probably in arch/ppc/8260_io/fcc_enet.c and make sure you have it configured for Tx and Rx clock coming in on the right pins, and also check that you are configured for the correct PHY interrupt.

But (tell me if I'm wrong) this is not really Linux code, and this should be done by Linux. What I think should be good also is the platform files (arch/ppc/platforms/....) for this is the place where all the board dependant stuff stays. Maybe I'm completely mistaken.

U-Boot is supposed to boot the "uImage" images, which do not issue such messages.
