[U-Boot] [RFC] - sanve the server's mac address...

[Robin Getz]

On Wed 8 Jul 2009 14:50, Robin Getz pondered:
> Linux's netconsole works much better when you can pass it the MAC
> address of the server. (otherwise it just uses broadcast, which
> everyone else on my network complains about :)
> 
> This sets the evn var "serveraddr" (to match ethaddr), so that you 
> can pass it to linux with whatever bootargs you want to....
> 
> addnetconsole=set bootargs $(bootargs) netconsole=@$(ipaddr)/eth0,@$(serverip)/$(serveraddr)
> 
> I'm sure this is white space damaged - but you get the idea...

Wolfgang - did you want me to push this through the Blackfin tree
(via Mike) or wait for Ben?
