[U-Boot-Users] problem with S29GL128N flash using cfi driver

[nicky geerts]

update:  the cfi driver in the version 1.1.0 displays:

so that's a success

however, when changing and saving environment variables, I get:

=> saveenv
Saving Environment to Flash...
Protect off FFFA0000 ... FFFBFFFF
Error: start and/or end address not on sector boundary
Error: start and/or end address not on sector boundary
Error: start and/or end address not on sector boundary

I'll keep searching :-) i'll take a look at the changes in the cfi
flash driver, and at my settings, maybe I screwed up something in the
sector sizes
