[ECOS] Redboot v1.92 IXP425 Board w/o EEPROM

[<s.s-c-h-m-i-t-t@web.de>]

Hi,

I know this issue was discussed recently, but, however, 
the following hint did not work for us:

 Mark Salter <msalter at redhat dot com> said:

The problem: We have a IXP425 based board very close 
to the IXDP425 development platform, but WITHOUT EEPROM!

That means: Redboot v1.92 messages errors when trying 
to read the EEPROM and does not find a network interface.

How do we have to modify the Redboot 1.92 sources to let 
it compile with one NPE  as network interface, e.g. storing 
the MAC address in Flash?

Cheers,
Stefan.
