From: Tom Lendacky <thomas.lenda...@amd.com> This patch series provides fixes for using TPM support with an SEV-ES guest.
The fixes include: - Decode ModRM byte for MOVZX and MOVSX opcodes. - Add MMIO support for MOV opcodes 0xA0-0xA3. - Create a new TPM MMIO ready PPI guid, gOvmfTpmMmioAccessiblePpiGuid - Mark TPM MMIO range as un-encrypted during PEI phase for an SEV-ES guest and install the TPM MMIO ready PPI guid.
