Hi,
From: Fabio Estevam <[email protected]>
Add the JEDEC ID for the XMC XM25QH128C SPI NOR flash.
This is a 128Mbit device using 64KiB sectors and supporting 4KiB
erase, dual read and quad read, matching the other XM25QH128 variants.

It would be nice to have Link: tag followed by datasheet URL [1].
I'll add the link when applying (I'm targeting the next branch, open in
a bit more than a week from now), no need to send a v5 for that.
Please still answer Takahiro's question below when you have time.
Thanks!
Quentin

Per the datasheet, this chip supports Dual/Quad ops but for my reference,
could you let me know if you tested 1-1-4 or 1-4-4 ops?
Anyway,
