Boot with NFS on MIPS32

[Chris Craig]

I believe you need to enable "Kernel level autoconfiguration" which is 
under Networking->Networking support->Networking options->TCP/IP 
networking (IP_PNP), and then you'll have a "Root file system on NFS" 
option (ROOT_NFS) available under Network File Systems.
