[flashrom] flashrom cannot write on ecs-A785GM-M7

[Beeblebrox]

As you have requested, from recently built flashrom in git repo:
/sourcefiles/flashrom> # ./flashrom -p internal --output readlog.txt -r
backup.bin
IMC MBOX: Timeout!
Shutting down IMC failed.
FAILED!
FATAL ERROR!
Error: Programmer initialization failed.

I assume 0.97 <= HEAD (?). Logfile attached. I am going to go ahead and
flash the BIOS using some other method. Will try and continue to support
your info/test requests in the mean time.
Regards.

Writes have been disabled for safety reasons because the presence of the IMC
was detected and it could interfere with accessing flash memory. Flashrom will
try to disable it temporarily but even then this might not be safe:
when it is reenabled and after a reboot it expects to find working code
in the flash and it is unpredictable what happens if there is none.

To be safe make sure that there is a working IMC firmware at the right
location in the image you intend to write and do not attempt to erase.

You can enforce write support with the amd_imc_force programmer option.
IMC SIO is at 0x4e.
IMC MBOX is at 0x3e.
