This series of patches adds support for disabling the TPM 2 platform
hierarchy to Ovmf. To be able to do this we have to handle TPM 2
physical presence interface (PPI) opcodes before the TPM 2 platform
hierarchy is disabled otherwise TPM 2 commands that are sent due to the
PPI opcodes may fail if the platform hierarchy is already disabled.
Therefore, we need to invoke the handler function
Tcg2PhysicalPresenceLibProcessRequest from within
PlatformBootManagerBeforeConsole. Since handling of PPI opcodes may require
interaction with the user, we also move PlatformInitializeConsole
to before the handling of PPI codes so that the keyboard is available
when needed. The PPI handling code will activate the default consoles
only if it requires user interaction.
Regards,
Stefan
