I cannot comment on code I've never seen.
Is it included by

Otherwise I don't know where else I could have this option enabled.
No, it is not.
Yeah, thats right. I have to protect our customers to fry their boards, not me :)
Just set up a service to recover these boards, and get rich ;-)
Seems you have configured U-Boot like that. On systems for which I am responsible attempts to TFTP to flash will not do harm.
tftp to flash does no harm. It is the mapped Area which is not protected by an default load adress when typos occur.
What is a "mapped area"?
Reading this I agree to you unlocking, erasing is not possible on increasing adresses. Otherwise IIRC I think the whole block can be unlocked and erased on different access adresses inside the block!
Otherwise how is it possible typos fry the flash device?
I am using intel 28F128J3...
Your flash driver does not drive the VPEN pin, it seems?
I think I will replace tftpboot an cp commands for customers by two argument less firmware - linux kernel or rootfs - commands.
I don't think this is a good idea. The software should behave as documented, and U-Boot documentation does not contain such arbitrary limits (nor do I like them).
