At the moment, as I understand things, FIS implies io/flash, which pretty much implies NOR. I don't have any plans to implement FIS on top of NAND; people who do use NAND will generally be using a filesystem, so "obviously" the right place to put static config data is on that filesystem? (Chicken, meet egg?) Now, if we were to need to write a primary bootloader - say, if a OneNAND-based SOC came into the frame and we wanted to run RedBoot on it - then we might very well find ourselves needing something along these lines. A very very simple filesystem, combined perhaps with the ability to store a little config data and/or partition table layout, for which it might be worth considering reusing some or all of the FIS code? With that in mind, I suppose that defining a scheme for a partition table and very simple FS for NAND would be a worthwhile exercise, which could then of course be contribbed to Linux. Comments?
