-- This header can also be reused to support EFI stub for RISC-V in future. EFI
- specification needs PE/COFF image header in the beginning of the kernel image
- in order to load it as an EFI application. In order to support EFI stub,
- code0 should be replaced with "MZ" magic string and res3(at offset 0x3c) should
- point to the rest of the PE/COFF header.
