PS7, Line 12: Making probe functions static and always using them uncovered that
            : bootblock stage included TPM driver which it didn't use.  This is why
            : Makefile.inc files were updated to replace `all-*` with
            : romstage, ramstage and verstage.

TPM is also setup in verstage which doesn't have to be a separate stage and may run/start in bootblock instead. Then I think the drivers might be needed.
