I also did some research on this ML, looking for some details about this topic, finding not so much more the original RFC thread: http://thread.gmane.org/gmane.linux.drivers.devicetree/72230/ I search for this kind of information inside various MLC NAND datasheets that I've available on my desk but I cannot find any reference on this, maybe is called in a different way or maybe I'm looking to the wrong devices (e.g. I'm currently working with some Micron NANDs MT29F32G08CBADA, MT29F32G08CBACA..) I CCed Boris and Jeff directly because maybe they can help me in better understanding the impact of this problem on some real device. TIA & BR, -- Andrea SCIAN DAVE Embedded Systems
