I've recently flashed coreboot with SeaBIOS and discovered that you
folks have added some support in the boot menu to configure the TPM
since I last used SeaBIOS.

Now, I never had any direct contact to TPM and only know roughly what
it does. As far as I know it's used as a cryptographic coprocessor
among other things.

The menu's options confuse me:
d. Disable the TPM
v. Deactivate the TPM
p. Prevent installation of an owner

Why would I want to activate or deactivate it? What's the difference
between disabling and deactivating?
And who's the owner? What's this good for?

The only thing I'm concerned about is that some troll could do
something fishy with this when having access to the machine.

Would I suffer negative consequences if I disabled TPM support in
SeaBIOS config before building?

Cheers
P.
