In the provided schematics only NAND devices are connected to the IFC.

NAND has to be accessible after QSPI boot assuming that RCW with correct signals multiplexing is applied.

There are no obvious errors in the QSPI_3.pdf.

There is no hardware issue with the design.

Please create separate question for the U-Boot "nand" issue.
