Sorry that I was absent and didn't know about the topic discussed on
Linux. The purpose of u-boot and Linux is quite different thought they
may share some code. The drivers are different, too. Whatever they chose
on Linux is not related here.

Marek did agree that "The behavior of this device is closer to CFI
flash.". This is what the core designed for, to replace the CFI flash. I
am more concerned with users. Users can use memory commands to display
and modify the content directly. This is very point where the driver
should stand.

Thanks.

Best regards,
Thomas
