-/**

-  Read the MCH_SMRAM and ESMRAMC registers, and update the LockState and

-  OpenState fields in the PEI_SMM_ACCESS_PPI / EFI_SMM_ACCESS2_PROTOCOL object,

-  from the D_LCK and T_EN bits.

-

-  PEI_SMM_ACCESS_PPI and EFI_SMM_ACCESS2_PROTOCOL member functions can rely on

-  the LockState and OpenState fields being up-to-date on entry, and they need

-  to restore the same invariant on exit, if they touch the bits in question.

-

-  @param[out] LockState  Reflects the D_LCK bit on output; TRUE iff SMRAM is

-                         locked.

-  @param[out] OpenState  Reflects the inverse of the T_EN bit on output; TRUE

-                         iff SMRAM is open.
