Hi Laurent,

The problem with these TPM chips is that they have the hidden purpose of
restricting you as user.  Despite that you paid for the hardware and are its
owner, the chip will never give you its master key.

The idea behind this is that you can be coerced into accepting that someone
else can spy on your computer (they call it "remote attestation").  When
enough users accept this form of blackmail, it will become impossible to
resist to it in practice.

For these reasons, I'd like to encourage you to consider the ethical
implications of using and supporting this technology, and look for
alternatives that would satisfy whatever needs you had in it (I'd welcome
some discussion about that, to see how GRUB can help).
