Series is also available at:
https://github.com/hwu25/edk2/tree/mpinitlib_opt_v1

This series will introduce a couple of optimizations to the MpInitLib with
regard to microcode:

A. Reduce the copy size when loading the microcode patches data from flash
   into memory;
B. Produce a HOB to contain microcode patches information for subsequent
   consumers of the microcode patches during the boot flow.

Uni-test done for the series:

A. System boot to OS/Shell successfully on a real platform;
B. Add debug message to verify the same microcode patch is applied to each
   processor before and after the series.
