In Charter 2.3.2 spec 2.4, it descripts SMBIOS tables should be
Runtime Service Type:
"In general, UEFI Configuration Tables loaded at boot time (
e.g.,SMBIOS table) can be contained in memory of type EfiRuntimeServicesData
(recommended and the system firmware must
not request a virtual mapping), EfiBootServicesData,EfiACPIReclaimMemory or
EfiACPIMemoryNVS. Tables loaded at runtime
must be contained in memory of type EfiRuntimeServicesData
(recommended) or EfiACPIMemoryNVS."
