[Buildroot] how can I change IP numbers when using 'defenv'?

[Mats Iderup]

Ok,

I find some hints.

U-Boot> defenv
U-Boot> run config
U-Boot> run get
U-Boot> bootm 21000000


New environment settings is fetched from
host /tftpboot/autoscript.at91sam9260dfc
when invoking the 'run config'.

Still bootargs holds old variables.

Perhaps also updated when I also build rootfiles......

thanks

Mats
