Now, I would like to use the cfi driver with the AT49BV6416 chip on atstk1000 instead of the custom driver, but unfortunately, it doesn't work. I'll have a closer look at it later (I think it's a combination of the geometry reversal issue and a special non-intel unlocking algorithm.)
Try the latest cfi driver from git. My patch to address geometry reversal for AMD style flash was applied today.
Thanks, but I already tried the latest patch I could find in my inbox. After I added a special case for AT49BV6416, it got the geometry right, but it still needs to learn how to "soft unlock" sectors before erasing/programming.
We could of course just unlock the whole thing at initialization time, like Linux does. AMD-style chips aren't supposed to be locked after reset.
