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

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.
