If I may ask for a few (1-2) days, so I can test this code on vf610 NXP SoC.

You're probably mixing that up. This series is about the FlexSPI controller in the Layerscape SOCs. The QuadSPI driver is already in linux-next to be merged in 5.1 [1]. The issues with vf610 existed in the old SPI-NOR driver and probably still exist in the new SPI driver. You are welcome to test the new driver and come up with some fixes. Sooner or later, there will probably also be other changes coming up, such as implementation of the dirmap API.
