Do you want to access files on your pc from ts-7200 via nfs? Or do
you want to boot ts-7200 using rootfs on your pc?

Try adding "root=/dev/nfs" to your exec command line. I also found
I needed to add an "ip= ... " to my command line. In your case I
guess it would be "ip=10.172.1.44", but you may not need it.
Are you sure /nfsroot is exported on your server, and is a valid arm
rootfs?
Finally, be sure when you do get NFS working, that your init scripts
don't change the IP address from 10.172.1.44, or else you'll loose
your rootfs.
