[RFC PATCH 0/4] Fix and improve gpmi nand on mx28
From: Dario Binacchi
Date: Fri Dec 17 2021 - 10:55:52 EST
Starting from [1], the series fixes the timings setting of the gpmi
controller for the mx28 architecture, also adding support for fast
edo mode timings. The whole series has been heavily tested with the
mtd kernel test modules, and with repeated write cycles on nand.
The patches of the series were applied after applying patches [2]
and [3] which at the moment are already in nand-next.
