Subject: [PATCH 0/4] Fix and improve gpmi nand on mx28

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 whole series has been tested and reviewed by Sascha Hauer <s.hauer@...gutronix.de>,
so I removed the RFC prefix and re-submitted it as a regular patch
set by adding the 'Tested-by' and 'Review-by' tags to every single patch.
