That is the idea. It is supposed to work this way as far as I 
understand. Don't change this behavior...

If you have not done already, I think you should enable hardware (real) 
flash protection (CFG_FLASH_PROTECTION) in your board config file.

Upon boot do you see all sectors reported (RO) if you use flinfo command?

If not, you should look at the initialization of flash_info[].protect[] 
within flash_get_size() which is called from flash_init().

If this array is not initialized properly, U-Boot might attempt to erase 
a locked sector/block incorrectly instead of bailing out nicely. I think 
"saveenv" would have trouble as well. If this is the case, perhaps, 
FLASH_OFFSET_PROTECT and FLASH_STATUS_PROTECT is not appropriate for 
your type of flash and you should work on a solution for this instead.
