It looks like the wrong file was modified. That probably causes
Orochi code to be used instead of Trinity as desired. Only change
the one file in the family15tn directory:

diff --git a/src/cpu/amd/agesa/family15tn/model_15_init.c b/src/cpu/amd/agesa/family15tn/model_15_init.c

 };


Here is an optional change. That first hack that changes == to != is
quite unreadable and confusing. I believe the following is a better
solution. Also remember that running Trinity agesa on Richland is a
hack and hopefully a temporary solution. Possible problems are:
1) desired microcode patch is not available 2) Any Richland errata
workarounds embedded in the agesa code are not present 3) There
might be some differences between Trinity and Richland recommended
register settings.
