   This works but the created file doesn't survive a remount.

   BTW, during boot I'm seeing with thsi driver:

spi spi0.0: setup: ignoring unsupported mode bits 800                           
spi-nor spi0.0: Failed to parse optional parameter table: ff81                  

   (The 2nd message is also seen with my drivers).
