As described in the README. A new cpu directory is only  needed  when
you add support for a new processor.

You cannot boot over NFS - that would require TCP/IP and a lot  more.
U-Boot can only use DHCP/BOOTP/TFTP for network booting.

Of course you have to make sure that your network driver gets  hooked
into the network routines.

Just use the commands "loads" or "loadb".

Normally you don't need to do anything in a CPU  specific  directory.
Follow the instructions in the README.

You know that feeling when you're leaning back  on  a  stool  and  it
starts to tip over? Well, that's how I feel all the time.
