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.

CHANGELOG:

* Update ethaddr handling on CMC-PU2 board

I disagree. If you need this, pass the u-boot environment to the linux kernel, or add a serial# member in bd_t.

I reject this patch. SO far we never to automatically modify environ- ment in flash. All the other TQ boards which do similar things just read the data and set it in the environment, but don't automatically safe it to flash.
