IMX6UL - Max QSPI memory capacity

Dear All,


The IMX6UL datasheet says the max memory map for QSPI is 256MB.

However, understand that IMX6UL has two QPSI Buses (Bus A and Bus B), each has two chip selects (SS0, SS1). If we configure each QSPI bus as parallel mode, does it mean the total QSPI flash capacity can be extended to 256MB x 2 = 512 MB? Thanks in advance.
