I am investigating this and, as I indicated to Ben, submit
a follow up patch to  implement it if I figure out to do it.

Well, by the time Linux is running, there is no more firmware
available.  Linux is essentially autononomous at this stage,
and I think it will have to arrange for the TB sync itself.
