Update ethaddr handling on CMC-PU2 board
Patch by Martin Krause, 16 Nov 2005

If the environment variable 'ethaddr' is not set in flash it is read from
EEPROM (if valid), set in RAM and now also saved to flash. The same applies
for the variable 'serial#'.
This is done to optimise series production. Now, no 'saveenv' command
has to be applied over the serial line. And thus no serial connection
is necessery at all. Setting ethaddr only in RAM is not sufficient,
because 'ethaddr' and 'serial#'  must be readable from linux with the 
fw_printenv tool.
