Hi,

I have problem with the driver. I'm not sure where the problem is.
Without calling sspi first, sf probe doesn't work. I guess driver 
doesn't bind.

The output is:

=> sf probe
Invalid chip select 0:0 (err=-19)
Failed to initialize SPI flash at 0:0

Maybe I'm missing something?

Regards,
Stefan Mavrodiev
