Yes, w/o this constrain it would be okay to request locality only once, 
we can ask tboot ask again but at the time the requirement was that locality can be taken of at any point, 
I believe that the locality won't be granted till a single command is completed.

But then tboot could race between requesting a locality and sending
the command (like immediately after the locality has been granted).

Anyhow still the power gating is wrong in this patch do not ignore
that part.

I can certainly take steps back with gating. It is not a blocker for
other changes but I do need to explain it in the changelog what problem
does cause. I'm not ignoring it. I just don't understad what is wrong.

Thanks
