Hi Scott,
I've recently contributed a lot of MTD/NAND related patches (and intend to continue doing so). Some of them are transversal changes touching the MTD and NAND framework internals, which implies patching all NAND drivers along with the core changes.
All those changes are required to properly handle modern NANDs (MLC/TLC NANDs), and I need them to add proper NAND support to the sunxi platform (and more particularly to the C.H.I.P from NextThing Co.).
So my question is, how should I port those changes to U-Boot? I see that your doing "synchronization commits", but in my case this mean including a bunch of driver specific changes into this "sync commit".
I think it's also worth mentioning that I plan to heavily rework the Linux NAND framework to improve NAND performances on modern NAND controllers and clarify the NAND chip / NAND controller concepts, and other people are also working on merging the BBT code of the NAND and OneNAND framework. Which unfortunately means that we're not done porting invasive changes to U-Boot :-/.
Any advice is welcome.
Thanks,
Boris
