Honestly, the current spi flash code which deals with nor devices are
has some issue
like spi-nor specific logic is part of spi-bus like the situation was
Linux is in before "spi-nor"

We're working on the spi-nor[1] front, hopefully by next release we
might have some progress
on that, I recommend you to start spi-nand as you're trying for Linux.
I would help you at any point
as I'm going to work on this spi-nor.
