I have a slight issue which I could not resolve regarding the Hynix
NAND on this platform. Although it worked perfectly well with 3.12,
the device is not detected anymore with the current head of master.
There is no warning nor bug that I could find. It just not detected.
Since I don't really know how to debug this, maybe doing git bisect ?
Some advice would be greatly welcomed !
