Thanks for the tip.
Now I am using uImage file to boot MV Kernel from U-boot on Embedded Planet 
EP8260 board. But it seems to be stuck after uncompressing:

 

=>tftp 0x400000 uImage.ep8260
ARP broadcast 1
TFTP from server 10.0.0.1; our IP address is 10.0.0.2
Filename 'uImage.ep8260'.
Load address: 0x400000
Loading: #################################################################
         ###############################################################
done
Bytes transferred = 655335 (9ffe7 hex)

=> imi    
## Checking Image at 00400000 ...
   Image Name:   MV Linux Kernel Image for EP8260
   Created:      2003-07-10  13:09:51 UTC
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    655271 Bytes = 639.9 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK

=> bootm 0x400000
## Booting image at 00400000 ...
   Image Name:   MV Linux Kernel Image for EP8260
   Created:      2003-07-10  13:09:51 UTC
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    655271 Bytes = 639.9 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Nothing happens after this…….

I tried to enable the Pipeline in the boot which results in some extra 
characters after "Uncompressing Kernel Image ... OK". 

 

I used following to make uImage.ep8260 file

../u-boot-0.3.0/tools/mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -
n "MV Linux Kernel Image for EP8260" -
d /prj3/kernel/arch/ppc/boot/images/vmlinux.gz /tftpboot/uImage.ep8260


Thanks
