ASRock Z390M-ITX/AC: firmware is corrupted or missing

[dtbartle]

When running ./me_cleaner.py --check <bios> I get:

Full image detected
The ME/TXE region is valid but the firmware is corrupted or missing

I tried this on the publicly available BIOS files (1.10 and 1.20) as well as BIOS files dumped from my motherboard (which actually differ a fair bit from the "stock" BIOS files for some reason).

It looks like for whatever reason, me_cleaner ends up getting the ME region wrong. I can find $FPT in the file (at 0x4000), while me_cleaner thinks it's at 0x3000.

CSME 12 is not supported by me_cleaner as the CNP CSE region of the SPI chip uses a new structure called CSE Layout Table which combines IFWI v1.6 (BPDT v1) for Code and $FPT v1.0 for Data/FS partitions.

did you dump it twice and use the diff command to make sure it's dumping correctly?
Maybe we should be more quiet about this. What causes them to change structures?

[dtbartle]

Yes. I also tested against stock BIOS files.

Would you mind testing #282 ?
Soft disable might work as expected. I'm having success with a similar board.

[dtbartle]

Yes, confirmed your PR works for this board.
