Feature #16405

Updated by Robert Mustacchi 2 months ago

As AMD has started publishing family 0x1a support into Linux, we should follow suite initial support for this family. This covers initial cpuid socket and family detection for the system as well as the @amdzen@ nexus driver. 

 One thing to call out is that the DF memory controller pieces that are added as part of this work, that we call @4D2@, are actually things that relate to more than just family 0x1a. We have seen it used in phoenix and other parts.
