2012-03-01 | When CSM uses EFI_SEGMENT and EFI_OFFSET to call CSM16 function, some CSM16 ↵ | li-elvin | |
use es:[offset + 0xabcd] to get data passed from CSM32, offset + 0xabcd could exceed 0xFFFF which is invalid in real mode. So added NORMALIZE_EFI_SEGMENT and NORMALIZE_EFI_OFFSET to keep offset as small as possible to avoid this issue during CSM16 function call.
