Thanks for the report. While many people overlap with the flashrom
list, please post about those patches on that list. Seems that you
should be able to ack them.
It looks like maybe the platform build doesn't support your CPU.
There have been a number of recent contributions from AMD, but they
don't all align with the platform contributions. So, the H8SCM should
support all fam10 revD, but may have issue with Fam10 rev E. To get
more information, you can turn the console debug output to SPEW in
