Hi Norman,

Thank you for merging the patch :)

Ok.

Thanks for the info. I have never seen this option elsewhere - everybody else 
just seems to specify the libraries several times.

Also the data cache issue is definitely not coming from DOpE, but from the Xst 
synthesizer we use for generating the FPGA bitstream.
We tried running Linux and DOpE on the same HDL code with the data cache 
enabled but synthesized by Synplify (from Synopsys). They work as if the data 
cache was not there (but they're faster).

Cheers,
Sébastien
