x86_smm interface.
The get_state method saves the cpu state in the state struct. This method is intended to be used during SMM entry.
The set_state method restores the cpu state from the state struct. This method is intended to be used during SMM exit.
The smram_read and smram_write methods can be used to access the SMRAM during SMM entry/exit.
This interface is internal and may change without notice.
