External Loader with 4-bit QSPI on XSPI1 for the MX25UW25645G on the NUCLEO-H7S3L8 demo board

[Duckpaddle]

Does anyone know of an existing external loader for the NUCLEO-H7S3L8 that uses the 4-bit QSPI rather than the more conventional 8-bit.  Because of shared pins on the demo board, I needed to use 4-bit QSPI for my build.
