Where can I find a NOR Flash controller that is supported by Qsys and SOPC Builder?

Description

NOR Flash controllers use what is referred to as a Common Flash memory Interface (CFI) to determine the operating parameters of the interfacing Flash memory. 

Altera's Flash Memory Interface (CFI) controller is Qsys compliant and SOPC Builder-ready, with its Avalon interface, and can be used to interface to NOR Flash memory devices.  This core is available in the in these system integration tools.  See link below more details on this controller:

The Wikipedia link below provides detailed explanation on both NOR and NAND Flash memory types.
