REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1584 The flow of CPU feature initialization logic is: 1. BSP calls GetConfigDataFunc() for each thread/AP; 2. Each thread/AP calls SupportFunc() to detect its own capability; 3. BSP calls InitializeFunc() for each thread/AP. There is a design gap in step #3. For a package scope feature that only requires one thread of each package does the initialization operation, what InitializeFunc() currently does is to do the initialization operation only CPU physical location Core# is 0. But in certain platform, Core#0 might be disabled in hardware level which results the certain package scope feature isn't initialized at all. The patch adds a new field First to indicate the CPU's location in its parent scope. First.Package is set for all APs/threads under first package; First.Core is set for all APs/threads under first core of each package; First.Thread is set for the AP/thread of each core.
