commit 3b3ba6ab2fabe406d0db7d798a78cdf4562b8d44
Author: Sergej Ivanov

vendorcode/amd/agesa/f16kb: Enable support for AM1 socket

Adds option FORCE_AM1_SOCKET_SUPPORT to disable
    package type mismatch check between cpu and northbridge.
    Default agesa for kabini doesn't know about AM1 socket
    so it returns FALSE, that stops memory config code.
    With this hack current agesa version supports the AM1 socket.
