Marc-André Lureau ffab1be706 tpm: clear RAM when "memory overwrite" requested ... Note: the "Platform Reset Attack Mitigation" specification isn't explicit about NVDIMM, since they could have different usages. It uses the term "system memory" generally (and also "volatile memory RAM" in its introduction). For initial support, I propose to consider non-volatile memory as not being subject to the memory clear. There is an on-going discussion in the TCG "pcclientwg" working group for future revisions. CPU cache clearing is done unconditionally in edk2 since commit d20ae95a13e851 (edk2-stable201811).
