49 TemporaryRamDone() disables the use of Temporary RAM. If present, this service is invoked
50 by the PEI Foundation after the EFI_PEI_PERMANANT_MEMORY_INSTALLED_PPI is installed.

53 @retval EFI_INVALID_PARAMETER Temporary RAM could not be disabled.
63 Entry point to the C language phase of SEC. After the SEC assembly
64 code has initialized some temporary memory and set up the stack,
65 the control is transferred to this function.
