If tools-only is for tools, only, then why should it enable LMB ? The tools are userspace tools, they do not need LMB, and so LMB can be disabled.
This is the part which is unclear to me.
I don't know why it's unclear to you at this point, sorry.
Well why exactly does a userspace program require LMB enabled ? What does LMB protect in there ? obviously not U-Boot.
I feel like you've lost the thread.
Can you please answer my questions above ?
I have.
This attitude is not helpful. Please answer my questions, if necessary please reiterate, otherwise this discussion cannot be resolved and will only lead to frustration.
