Hrmf. It seems like I have been looking into the wrong datasheet.

The actual device is at25sf321, not at25s321b, where the former can not
be identified using the SFDP table.
At25sf321 and at25s321b uses the same JEDEC ID though, probably what got
me wrong in the first place.

Please see page 10 in
https://www.renesas.cn/zh/document/apn/an201-adesto-32mbit-products-overview
for further reading.

I will send a v2 with updated details.

Best regards,
Marcus Folkesson
