commit f6dd36070de3bc3ee3ad61b0d969f127f1dfeb95

    vendorcode/amd/agesa/f16kb: Enable support for AM1 socket
    
    Adds option FORCIBLY_ENABLE_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 will supports AM1 socket.
