Could you add that as a "Datasheet:" tag before your Sob tag?
This chip has been (briefly) tested on the MediaTek MT7688 based GARDENA
smart gateway.
Could you also apply my SFDP patch [1] and send the dump? Unfortunately,
I can't think of a good way to do that along with the patch and if this
in some way regarded as copyrighted material. So feel free to send it to
me privately. I'm starting to build a database.
NB. XMC ignores the continuation codes and this particular device will
collide with M25PE64/M45PE64. Although I couldn't find any datasheet,
so I don't know if these devices actually exist.
