Applied to u-boot-nand-flash with the diff below. Do you know if all chips that support locking support the invert bit? If not, we should at least update the documentation to mention this (though runtime detection would be good if practical).
I'm not aware of a part that supports lock and not the invert functionality. I'm also not aware of a way to detect at runtime if it is supported.
Thanks, -Joe
