+ Restores the platform to its preboot configuration for an S3 resume and
+ jumps to the OS waking vector.
+
+ This function will restore the platform to its pre-boot configuration that was
+ pre-stored in the boot script table and transfer control to OS waking vector.
+ Upon invocation, this function is responsible for locating the following
+ information before jumping to OS waking vector:
+ - ACPI tables
+ - boot script table
+ - any other information that it needs
+
+ The S3RestoreConfig() function then executes the pre-stored boot script table
+ and transitions the platform to the pre-boot state. The boot script is recorded
+ during regular boot using the EFI_S3_SAVE_STATE_PROTOCOL.Write() and
+ EFI_S3_SMM_SAVE_STATE_PROTOCOL.Write() functions. Finally, this function
+ transfers control to the OS waking vector. If the OS supports only a real-mode
+ waking vector, this function will switch from flat mode to real mode before
+ jumping to the waking vector. If all platform pre-boot configurations are
+ successfully restored and all other necessary information is ready, this
+ function will never return and instead will directly jump to the OS waking
+ vector. If this function returns, it indicates that the attempt to resume
+ from the ACPI S3 sleep state failed.

+ Restores the platform to its preboot configuration for an S3 resume and
+ jumps to the OS waking vector.
+
+ This function will restore the platform to its pre-boot configuration that was
+ pre-stored in the boot script table and transfer control to OS waking vector.
+ Upon invocation, this function is responsible for locating the following
+ information before jumping to OS waking vector:
+ - ACPI tables
+ - boot script table
+ - any other information that it needs
+
+ The S3RestoreConfig() function then executes the pre-stored boot script table
+ and transitions the platform to the pre-boot state. The boot script is recorded
+ during regular boot using the EFI_S3_SAVE_STATE_PROTOCOL.Write() and
+ EFI_S3_SMM_SAVE_STATE_PROTOCOL.Write() functions. Finally, this function
+ transfers control to the OS waking vector. If the OS supports only a real-mode
+ waking vector, this function will switch from flat mode to real mode before
+ jumping to the waking vector. If all platform pre-boot configurations are
+ successfully restored and all other necessary information is ready, this
+ function will never return and instead will directly jump to the OS waking
+ vector. If this function returns, it indicates that the attempt to resume
+ from the ACPI S3 sleep state failed.
+

+ @retval EFI_ABORTED Execution of the S3 resume boot script table failed.
