Routine Description:\r
\r
  This is the standard EFI driver point that detects\r
  whether there is an proper chipset in the system\r
  and if so, installs an SMM Access Protocol.\r
\r
Arguments:\r
\r
  ImageHandle  -  Handle for the image of this driver.\r
  SystemTable  -  Pointer to the EFI System Table.\r
\r
Returns:\r
\r
  EFI_SUCCESS      -  Protocol successfully started and installed.\r
  EFI_UNSUPPORTED  -  Protocol can't be started.\r

\r
Routine Description:\r
\r
  This routine accepts a request to "open" a region of SMRAM.  The\r
  region could be legacy ABSEG, HSEG, or TSEG near top of physical memory.\r
  The use of "open" means that the memory is visible from all boot-service\r
  and SMM agents.\r
\r
Arguments:\r
\r
  This             -  Pointer to the SMM Access Interface.\r
  DescriptorIndex  -  Region of SMRAM to Open.\r
\r
Returns:\r
\r
  EFI_SUCCESS            -  The region was successfully opened.\r
  EFI_DEVICE_ERROR       -  The region could not be opened because locked by\r
                            chipset.\r

  EFI_DEVICE_ERROR       -  The region could not be closed because locked by\r
                            chipset.\r

Routine Description:\r
\r
  This routine accepts a request to "lock" SMRAM.  The\r
  region could be legacy AB or TSEG near top of physical memory.\r
  The use of "lock" means that the memory can no longer be opened\r
  to BS state..\r
\r
Arguments:\r

  This             -  Pointer to the SMM Access Interface.\r
  DescriptorIndex  -  Region of SMRAM to Lock.\r

Returns:\r

  EFI_SUCCESS            -  The region was successfully locked.\r
  EFI_DEVICE_ERROR       -  The region could not be locked because at least\r
                            one range is still open.\r

Routine Description:\r

  This routine services a user request to discover the SMRAM\r

  memory controller capabilities.\r
