As for TPM, I don't see the point. This should not stop us in using it on amd64 if available. I think one =20 of the problem was/is the lack of time/man-power. So if someone comes =20 up with a good (enough) implementation which works on our supported =20 hardware, I don't think it will be rejected. Regarding TPM: there are good an bad uses for it. As our policy is to =20 provide possibilities and not to force policies on our users, I don't =20 see a reason why we will not incorporate good code regarding this. I =20 also think that we don't have it, as nobody needed it or wasn't =20 allowed to contribute code. But all this is better suited for arch@ I think (or maybe amd64@ in =20 case of NX).
