Well; you blocked olinuxino patch until mxsboot where ported and the dd with offset were not a solution for you, ... so ... I prefer to have this as is and share documentation with mx28. The NAND ought to be done providing same interface so one doc for it all. I think change it in next version is wrong and confuse users. -- Otavio Salvador O.S.
