Zynq US+ PS DDR size wizard (clamshell topology)

Hi,

Configuring DDR of Zynq UltraScale+ MPSoC PS using clamshell topology with 3x8191MBits dies (32bits +ECC), Vivado seams to compute a DDR Size of 4GBytes instead of 2GBytes.
I may missed something, but I suppose that will not prevent DDR controller to work as expected.
However, perhaps wizard could be improved.

Thanks,

Olivier
