/** @file
Provides the data format and Name and GUID definition for the EFI Variable ACPI_VARIABLE_SET and the Framework version's correponding
EFI Variable.
This variable is the persistent data that will be saved to NV EFI Variable. It is the central repository
for configuration data saved by the CPU Driver, Platform SMM Handler. It is read by
Platform PEIM and PEIM on S3 boot path to restore the system configuration.
