[flashrom]MX25L1605A and MX25L1605D

Hello

Anyone can tell me how to make the difference between the 1605A and the 1605D ?

differenciate both ?
I check the datasheets, but... see no differences in RDID or REMS.

What happens if you send an unsupported opcode? Can you use that to
differentiate?

We'd have to check with Macronix developer services. The default
reaction to unknown opcodes on many chips is to ignore them, though. SPI
does not provide any way for the chip to return error codes.
