Damage Maps

[travisgoodspeed]

When disassembling code from a ROM dump, the dump is often incomplete, with some region of bits being either poorly etched or poorly stained. Close this ticket when GoodASM can accept a bitmap of damage along with the firmware binary.

• CLI parameter to import a damage mask.
• Listings comment damaged instructions.
• Graders can avoid damaged regions.
• GUI integration in MaskRomTool.

Use -D to display damage bits and --damage foo.bin to load a mask file of the damaged bits. 1 is damaged, 0 is undamaged.
