The former would likely be better as I'm not sure Paul has the time
to respin the patch. My recollection is that TPH save/restore support
was dropped as a requirement for the Intel device this was originally
developed for, but it would be a shame to lose the time and effort
that already went into it and I think it might be useful for your
use case as well to support reset recovery.

Indeed, good job!
Thanks for taking a look!
