That flash should support SFDP, so please try the following:
+ { "w25q01jvm", INFO(0xef7021, 0, 0, 0) PARSE_SFDP },
Also, we require an SFDP dump for new flash submissions, see [1].

It looks like this was already attempted to be added:

Potin, do you have an update?

It seems like QEMU doesn't support SFDP yet. Is using PARSE_SFDP a hard
requirement or can we delay until the QEMU support can be written?

It turns out that there is some tentative support in QEMU for giving
SFDP information now. I've sent a patch building on top of that for the
w25q01jvq chip and updated Potin's patch-set to v4 that I mentioned
elsewhere in this thread.
It looks like the w25q01jvq I pointed to in Potin's patch-set and the
w25q01jvm being proposed here are slightly different chips.

It turns out that there is some tentative support in QEMU for giving
SFDP information now. I've sent a patch building on top of that for the
w25q01jvq chip and updated Potin's patch-set to v4 that I mentioned
elsewhere in this thread.
It looks like the w25q01jvq I pointed to in Potin's patch-set and the
w25q01jvm being proposed here are slightly different chips.

Hi!
The flash entry is not really needed as all its features and parameters
are initialized by parsing SFDP, so we can instead use the spi-nor-generic
driver that was introduced by Michael at:
https://lore.kernel.org/linux-mtd/166903807811.85501.6803386075881922742.b4-ty@microchip.com/T/#t
