The iMX28 SPI module is flexible to work with 1, 2 or 4 data pins, being then compatible with Quad SPI flash memories, per the discussion below it is also clear there are drivers available on the current BSP.

My question regards the possible limitations of working with that module, compared to newer QuadSPI controller IPs, like the one available on Vybrid for instance? Should we expect a lower performance on that controller, compared to newer IPs, for example the one available on Vybrid?
