-// This table to declare the generic SMM communication buffer location.
-// If this table is present, it means the SMM communication buffer is restricted to
-// EfiReservedMemoryType, EfiACPIMemoryNVS, or EfiRuntimeServicesData.
-//
-// This table is installed to UEFI configuration table by generic driver
-// or platform driver, at early DXE phase.
-// 
-// The EFI_MEMORY_DESCRIPTOR entry must contain at least one entry.
-// The entries must be normal memory region in EfiReservedMemoryType, EfiACPIMemoryNVS,
-// or EfiRuntimeServicesData.
-// If the Entry.Type is EfiConventionalMemory, it means this entry is free to use.
-// If the Entry.Type is other, it means this entry is occupied.
-//
-// Any non-SMM component may put communication data there, then use 
-// UEFI defined SMM Communication ACPI Table, or PI defined EFI_SMM_COMMUNICATION_PROTOCOL
-// to communicate with SMI handler. The process is:
-// 1) Find an entry whose type is EfiConventional.
-// 2) Change type to be EfiReservedMemoryType before use.
-// 3) Use it.
-// 4) Restore type be EfiConventional.
-//    The step 2) must be performed as an atomic transaction, if there might be conflict during runtime.
-//    For example, on IA-32/x64 platforms, this can be done using the CMPXCHG CPU instruction.
-//    If there is guarantee on no conflict during boot time, these steps can be skipped.
-//    For example, DXE, UEFI driver and UEFI application runs in sequence.
-//
-// For example, FPDT driver can use this communication buffer to get SMM
-// performance data in SMM. Profile driver can use this communication buffer
-// to get SMM profile data in SMM.
