Some of your recent cfi flash driver enhancements have made flash protect/unprotect work on our NOR based platforms (S29GL512). Good news so far, but as a consequence fw_setenv is woking no more: MTD erase error on /dev/mtd5: Input/output error Error: can't write fw_env to flash
Also flash_unlock from mtd_utils is not doing the trick: Could not unlock MTD device: /dev/mtd5
Unprotecting flash in u-boot before booting linux makes this work, but this is probably no good idea.
So what is the recommended workflow for fw_setenv on protected flash?
