/**\r
\r
  The InstallAcpiTable() function allows a caller to install an   \r
  ACPI table. When successful, the table will be linked by the   \r
  RSDT/XSDT. AcpiTableBuffer specifies the table to be installed.   \r
  InstallAcpiTable() will make a copy of the table and insert the   \r
  copy into the RSDT/XSDT. InstallAcpiTable() must insert the new   \r
  table at the end of the RSDT/XSDT. To prevent namespace   \r
  collision, ACPI tables may be created using UEFI ACPI table   \r
  format. If this protocol is used to install a table with a\r
  signature already present in the system, the new table will not\r
  replace the existing table. It is a platform implementation\r
  decision to add a new table with a signature matching an\r
  existing table or disallow duplicate table signatures and\r
  return EFI_ACCESS_DENIED. On successful output, TableKey is   \r
  initialized with a unique key. Its value may be used in a   \r
  subsequent call to UninstallAcpiTable to remove an ACPI table.   \r
  If an EFI application is running at the time of this call, the   \r
  relevant EFI_CONFIGURATION_TABLE pointer to the RSDT is no   \r
  longer considered valid.   \r
