Is it necessary to import the entire complexity of TSS for the measured
boot task of hashing the various components?  Once the Linux payload
starts up it can implement the more complex parts, as long as the
bootblock (with appropriate WP# and BP bits set on the ROM) can setup
the root of trust and the romstage/ramstage/payload loading process can
maintain the chain.
