interfaces.

You say _may_ ... wouldn't it be better if it was thus left to a given
virtex based platform to enable DCR_MMIO if it uses it and leave only
NATIVE by default ?

Yes, but this is a symptom of a separate problem, which is that it is
sometimes valuable to generate an optimized kernel configuration for a
particular FPGA system.  First order, I'm more concerned about getting a
kernel which is generic and can work with (more or less) any device
tree.
