[edk2] [Patch v2 0/2] Change CpuS3Data memory type and address limitation

Posted by Eric Dong 5 years, 8 months ago

Because CpuS3Data memory will be copy to smram at SmmReadToLock point by
PiSmmCpuDxeSmm driver, so the memory type no need to be ACPI NVS type,
also the address not limit to below 4G.
This change remove the limit of ACPI NVS memory type and below 4G.
