No there is no driver, Linux is not Windows and the RPi is a completely different architecture.
As for copying settings I'd just start from scratch, it's going to be easier.
I don't know why nothing has changed. Maybe if you go to the github page and raise this issue, I've tried with RPi5 SPI issue but have had no one make a reply.
In reality unless you need a something the size of the RPi you would get better bang for buck with a x86 system that has 2 spare PCIe slots for 2 Parallel Port cards to get about the same IO.
I got fed up with my RPi5 and added a EPP interface to the FPGA card I made and used that with a small ITX board.
