This guide will explain how to setup an EDK 12.1 project to interface with two 16-bit Atmel (AT49BV322D, AT49BV322DT, AT49BV322A, AT49BV322AT) Flash Memory parts organized in parallel acting as a single 32-bit Flash Memory using the Xilinx XPS_MCH_EMC IP Core.

Tweaking of the XPS_MCH_EMC Properties is necessary because this Flash Configuration is addressed like a 16-bit Flash but data is read & written like a 32-bit Flash. By default, the XPS_MCH_EMC is not setup to handle this situation.
