This is long lasting work that I did last few months back, I'm sure it's where much need now.
- spi driver: drivers/spi/fsl_qspi.c

making spi subsystem becomes more flash specific rather operating as a generic spi bus. So SF-NOR divides normal spi flash operations through generic SPI API's(sf_spi.c) and more spi flash(sf) specific operations through SF NOR API's.
So the controllers those are operating more on flash needs to write a driver on drivers/mtd/spi/ example fsl_qspi.c
I have not tested more accuratly as of now, will come back again with new feature additions/removal, zynq_qspi additions and more...
Note: dm-spi ops can gets effected with this new framework { .ops = &spi_flash_std_ops, } and will fix that in next version patches.

I have but a general question -- why did you not just import the spi-nor framework from Linux ?
Well, importing spi-nor from Linux is may not be a good idea as we have a working stuff at our end along with different dependencies and I'm sure this will becomes similar way as spi-nor at some point of time.
thanks!
