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@xxxxxxxxxxxxxx>, 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.
