If you setup serverip to point at your PC for board test&manufacture then 
you can do:

setenv bootcmd     tftp 21000000 autoscript.myboard     ;     autoscr 

in your default (compile time) configuration.

Connect Ethernet
Power Up
autoscript is downloaded and executed
LED starts to blink when ready.
Power Down
Next board...

The autoscript.myboard is regenerated for every new board so they get a new 
and other custom features..

I really do not see the harm in this.
