EFI_BOOT_SCRIPT_WRITE() interface is a var-arg interface.
Spec defines the order of parameters for
EFI_BOOT_SCRIPT_PCI_CONFIG2_WRITE_OPCODE as below:
typedef
EFI_STATUS
(EFIAPI *EFI_BOOT_SCRIPT_WRITE) (
IN CONST EFI_S3_SAVE_STATE_PROTOCOL *This,
IN UINT16 OpCode,
IN EFI_BOOT_SCRIPT_WIDTH Width,
IN UINT16 Segment,
IN UINT64 Address,
IN UINTN Count,
IN VOID *Buffer
);
But implementation assumes Segment is in the very end, after Buffer.
Similar spec/implementation gaps are also found for
EFI_BOOT_SCRIPT_PCI_CONFIG2_READ_WRITE_OPCODE.
The patch fixes the implementation to extract the arguments in
correct order.

This function is used to store an OpCode to be replayed as part of the S3 resume boot path. It is

assumed this protocol has platform specific mechanism to store the OpCode set and replay them

during the S3 resume.
|

the first opcode in the table (BeforeOrAfter is TRUE). The position which is pointed to by

Position upon return can be used for subsequent insertions.
