Re: [PATCH v2 3/4] dt-bindings: mtd: macronix,mx25l12833f: add SPI-NOR chip

[Erez]

Yes, I think we should.

Reading the specification provided publicly by Macronix.
For all the JEDEC IDs with the no SFDP flag in drivers/mtd/spi-nor/macronix.c
All of them have a new version or a new chip with the same JEDEC ID
that supports SFDP.
There are 2 chips that Macronix does not provide spec. in public.
I can ask Macronix technical support on these 2 chips.

"RDID"    "Part."         "Size"              "Status"          "SFDP
status according to spec. or new chip replacing with same RDID and
SFDP supported according to spec."
