Module Name:
SaveMemoryConfig.c
Abstract:
This is the driver that locates the MemoryConfigurationData HOB, if it
exists, and saves the data to nvRAM.

Routine Description:
This is the standard EFI driver point that detects whether there is a
MemoryConfigurationData HOB and, if so, saves its data to nvRAM.
Arguments:
ImageHandle - Handle for the image of this driver
SystemTable - Pointer to the EFI System Table
Returns:
EFI_SUCCESS - if the data is successfully saved or there was no data
EFI_NOT_FOUND - if the HOB list could not be located.
EFI_UNLOAD_IMAGE - It is not success
