[edk2-devel] Question: GenSec: Generating EFI_SECTION_RAW section

[Abhishek Shah via groups.io]

Hi Laszlo

Thanks for the hint. After adding below (based on inf file posted here),
I am able to see EFI_SECTION_RAW sections getting generated:

[Rule.Common.DXE_DRIVER.ACPITABLE]
  FILE FREEFORM = $(NAMED_GUID) {
    RAW ASL                |.aml
  }


Regards,
Abhishek
