Arria10 DDR4 Interface

When you attempt to create a width expansion X32 design using 2X16 device. You should not turn on ping-pong phy option. You only need apply all setting same like 2X16 device and change the DQ width to 32.

For ping-pong phy, you only need it when you need 2 independent controllers but you still want to share the same cmd/add pin. However, for CKE/CS/ODT, you still need a different ping for both device because we still need the switching between both devices.
