Notes
=====
- 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.
