586 This is an function to close the S3 boot script table. The function could only be called in \r
587 BOOT time phase. To comply with the Framework spec definition on \r
588 EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable(), this function will fulfill following things:\r
589 1. Closes the specified boot script table\r
590 2. It allocates a new memory pool to duplicate all the boot scripts in the specified table. \r
591 Once this function is called, the table maintained by the library will be destroyed \r
592 after it is copied into the allocated pool.\r
593 3. Any attempts to add a script record after calling this function will cause a new table \r
594 to be created by the library.\r
595 4. The base address of the allocated pool will be returned in Address. Note that after \r
596 using the boot script table, the CALLER is responsible for freeing the pool that is allocated\r
597 by this function. \r
598\r
599 In Spec PI1.1, this EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is retired. To provides this API for now is \r
600 for Framework Spec compatibility.\r
601 \r
602 If anyone does call CloseTable() on a real platform, then the caller is responsible for figuring out \r
603 how to get the script to run on an S3 resume because the boot script maintained by the lib will be \r
604 destroyed.\r
605 \r
606 @return the base address of the new copy of the boot script tble. \r
