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,
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?
