I have a similar AMD motherboard as you, and when I first tried playing
with flashrom at the end of August I installed flashrom on FreeBSD. I got
the same message as you:
"FCH device found but SMBus revision 0x61 does not match known values."

Well, I am retired and messing with computers is my hobby, so I thought
maybe trying a Linux would work better with flashrom, and installed Ubuntu.
I still got the same message, and no real answer until Rene' Rebe posted
this email on Oct 12:

https://mail.google.com/mail/u/0/?tab=wm&ogbl#label/coreboot%2Fflashrom/WhctKJWHzSmQKFLjFkZrdWlXtzblWZTQhgLHvjxvmljHgPQLwpSfpwJdZrBqSvCfxLDJskv

What I realized was that I needed to download the source, modify a line to
include my particular spi chip, compile and install flashrom myself. I
looked at the documentation, asked questions, and IT WORKED.
And, besides being able to read my flash chip with flashrom, I have been
able to use it to write a stock bios update from MSI on my x570
motherboard, and IT WORKED. The first place to look is here:

https://www.flashrom.org/Downloads

So look at  Rene's email & the flashrom download & install info, and ask
more questions. Most everyone here is very willing to help.

And, there is a fix in the works on Gerrit by the flashrom developers, but
it's not yet released.

You might enjoy the #flashrom & #coreboot channels on Freenode IRC.
Best of luck,
Clay
