Well, strictly speaking, these partitions are only for the socdk, the 
Altera dev kit.  Our sample designs and file systems expect this layout.

Therefore, these partitions are not required for any other dev kits, and 
can probably be left out.

Or, Steffen, if you have a standard layout you'd like to see, then put 
that in there.

I think some people will have to patch the layout regardless.
