IMHO, supporting a specific flash shouldn't be part of this patch.
In any case, why do you need this? If you can share the details about this device, it would be interesting for me to take a look.
This driver's open-coded, legacy-style flash detection is nasty, and the only reason I've kept it is to avoid breaking some wacky user with some old board. In fact, maybe we can just kill it so nobody thinks it's sane.
Flash detection is the NAND core's job, and duplicating it in the driver is not nice. Let's try to avoid it.
BTW, nand_ids.c seems to list a similar device:
EXTENDED_ID_NAND("NAND 4GiB 3,3V 8-bit", 0xD7, 4096, LP_OPTIONS),
