Micron part number MT25QL512ABB is supported by the Intel® FPGA Generic QUAD SPI Controller although our Embedded Peripherals IP User Guide has a list of devices which currently does not include the MT25QL512ABB but does include the MT25QL512ABA, where the only difference is the last character (A or B) which designates the Die Revision.
You can safely use the Micron part number MT25QL512ABB. This part number will be included in a future release of the Embedded Peripherals IP User Guide.
