1 - How does a user know whether the TPM will use CRB or FIFO - whether 
to specify tpm_tis.force=1 or not?

Or can that be specified any time, and it becomes a noop for CRB?

2 - module parameter?  Does that mean whatever distro dependent file is 
used for the boot parameters - grub.conf or some EFI file like grub.cfg.
