I find the Kernel Entry Address and Load address for ARM kernel. it is 0x8000. Now my system hangs after "Kernel panic: VFS: Unable to mount root fs on 01:00". The kernel has Ramdisk support,ext2 file system support.I dont know where i m doing mistake.
Hmm, this is more Linux related, you should ask these questions on arm-linux-kernel.

Any reason why you use an initrd on an embedded system? initrds are for mainstream distributions who want to completely modularize their kernels, and I doubt that this is what you have in mind ;)
Are you sure your memory map is ok? I don't know the IXPs, but on ARM you normally have flash at 0x0, so loading the Linux kernel to 0x0+0x8000 and loading the initrd to 0x0 is probably not the best idea.
Creating 2 MTD partitions on "IXP425 Flash": 0x00040000-0x00440000 : "image" 0x00440000-0x00fc0000 : "user"
This suggests that you want to boot from mtd0: add 'root=/dev/mtdblock0' to your kernel command line options.
If you really want to boot from the initrd make sure that your kernel does support it.
