Well, the boot roms don't know how to tftp either, so I wouldn't say mop
is a replacement for tftp. If you use the tftp/bootparams stuff, the
sequence is:

1. Get bootloader via mop.
2. Get system parameters through bootparams
3. Get kernel via tftp.
4. Mount root through nfs.

The dhcp/bootp way is:

1. Get bootloader via mop.
2. Get system parameters through dhcp/bootp
3. Get kernel via nfs.
4. Mount root through nfs.

On the server side in this case, item 3 and 4 can be handled as one, which
is nice.
