Hi Bjorn,

Many thanks for your effort! I appreciate it very much. :-)

We can identify the Nemo board at the boot time. See dmesg output: [    
0.061592] NEMO SB600 IOB base e0000000

@linuxppc-dev
Any other ideas? Maybe the same as we can identify the other P.A. Semi 
boards (Electra, Chitra, and Athena).

@Olof
Maybe you know how we can identify the P.A. Semi Nemo board at the run-time.

@Darren
Do you have an idea?

Thanks to all for your help.

Cheers,
Christian
