This leon3 design is tailored to the HPE_mini board from
Gleichmann Electronics:

http://www.ger-fae.com/Hpe_mini_ac2.html

The default configuartion (and pre-compiled bit files) contains
a leon3 configuration with SDRAM controller and Ethernet DSU.
The IP address for the ethernet DSU is 192.168.0.68 . The
'info sys' command in grmon returns the following report:
