Description

Hi, I have been trying to use fiano for automated DXE injection however both of my test firmwares has classic IFD bug with overlapping BIOS region ([example](https://doc.coreboot.org/mainboard/gigabyte/ga-h61m-s2pv.html#notes-about-the-original-firmware))

Manual editing with now unsupported [UEFITool v0.28](https://github.com/LongSoft/UEFITool/releases/tag/0.28.0) is working

Is there any way to force fiano work with such firmwares?

Research direction

The issue names no file, test, or entry point. Read the linked coreboot notes and compare them with fiano's behavior on firmware containing overlapping BIOS regions. Done would be a defined and tested way for fiano to read those firmwares, but the implementation scope is not specified.
