NAND device ID 0xd5 appears twice in nand_ids.c table

The problem is that there is no geometry information in the ID bytes for
the older parts with page size 512 bytes and below, which is the case
for the 4MiB part.  Unsure if anyone has compiled a dump of ID bytes for
the older parts so that there is some fixed pattern to rely upon to
differentiate.
