Which means we want to either delete the System ROM reservation, perform the System ROM reservation after other reservations from the e820 map, or improve the error handling.
What is the point in making reservation of a ROM which does not exist at all at its legacy physical location? It is disinformation. I would not reserve any ROM (system, video, etc.) when there is no ROM. The c0000-f0000 range is also wrongly converted from RAM to ROM by the kernel.
From what I could see the rest of those checks actually test for a
ROM signature. Regardless with my patch that switches the order the current error handling challenged code will simply drop those regions.
