Miquel,

Microchip supports a twin quad mode too, and micron has some flashes

https://lore.kernel.org/linux-mtd/20231125092137.2948-1-amit.kumar-mahapatra@amd.com/T/#mbe999dde1d29371183aa53089ef6f0087d6902a7

We shall consider them from the beginning. I guess we need to read
everything all over again.
