[Qemu-devel] [PATCH 1/4] ovmf: add and link with Tcg2PhysicalPresenceLibNull when !TPM2_ENABLE

[marcandre.lureau@redhat.com]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

This NULL library will let us call
Tcg2PhysicalPresenceLibProcessRequest() unconditionally from
BdsPlatform when building without TPM2_ENABLE.
