Looks quite weird to me. Looks like it was designed for XIP, but a
search for "cfi" was unsuccessful.

My guess is that even after you finished the coding, noone else would
use it, so you're on your own. Feel free to ask specific questions,
that's about it.

Maybe the best starting point would be the mtdram driver, adjust it to
this device for read-only access and later look at some flash drivers
when adding write, erase, etc. support.

A hardware debugger really helps, if you can get one.
