Exactly. Just have this pin work as GPIO, while the rest stays special
function. But then, some SoCs can not individually assign pins to special
functions but can only do that in groups. Maybe that's the issue here.
And then: currently an "sf write" is not restricted in the length of data
written. It would be limited due to the malloc needed for the patch.
