if I am not mistaken, you have to also set:
#define CFG_FLASH_PROTECTION 1
And you will have to set the environment variable "unlock" to "yes". This will unlock all non U-Boot special sectors by default upon powerup.
=> setenv unlock yes => saveenv
Alternative to setting "unlock" environment variable you will need to issue "protect off" for any locked sector that should be unlocked. This may be handy if you have other stuff on the flash which you would like to keep protected. One way to do this is via a u-boot script that is executed as part of boot. I think Intel chips (used to) preserve their last lock status and recent Spansion chips start all locked upon boot so you might not need unlock environment variable for your Intel part as well once you have the proper sectors unlocked (for example jffs2 areas)
