hv: tpm2: do tpm2 fixup for security vm ACRN used to prepare the vTPM2 ACPI Table for pre-launched VM at the build stage using config tools. This is OK if the TPM2 ACPI Table never changes. However, TPM2 ACPI Table may be changed in some conditions: change BIOS configuration or update BIOS. This patch do TPM2 fixup to update the vTPM2 ACPI Table and TPM2 MMIO resource configuration according to the physical TPM2 ACPI Table.

hv: quirks: SMBIOS passthrough for prelaunched-VM This feature is guarded under config CONFIG_SECURITY_VM_FIXUP, which by default should be disabled. This patch passthrough native SMBIOS information to prelaunched VM. SMBIOS table contains a small entry point structure and a table, of which the entry point structure will be put in 0xf0000-0xfffff region in guest address space, and the table will be put in the ACPI_NVS region in guest address space. v2 -> v3: uuid_is_equal moved to util.h as inline API result -> pVendortable, in function efi_search_guid recalc_checksum -> generate_checksum efi_search_smbios -> efi_search_smbios_eps scan_smbios_eps -> mem_search_smbios_eps EFI GUID definition kept Tracked-On: #6320 Signed-off-by: Yifan Liu <yifan1.liu@intel.com>
