For patch 2, address a typo to resolve enlarging the microcode patch information buffer too early when it is not full; B. For patch 4, relocate the logic of storing detected microcode patch before the application of microcode patch. V4 history: A. For patch 2, keep the calling sequence of functions: MicrocodeDetect() and MtrrGetAllMtrrs() unchanged for BSP. B. For patch 2, in function LoadMicrocodePatch(), add the missing logic that handles the Extended Signature Table of a microcode patch. V3 history: For patch 3, correct license information for newly added header file. V2 history: A. For patch 2, rename function parameters and variables to better reflect their usage; B. For patch 2, remove unneeded check in LoadMicrocodePatchWorker(); C. For patch 3, rename a couple of fields in the HOB structure; D. For patch 3, update the 'ProcessorSpecificPatchOffset' field to point to the microcode patch header instead of microcode patch data; E. Add a new patch 5 to address an issue that certain fields in the CPU_MP_DATA structure cannot be passed from PEI phase to DXE phase; F. Add a new patch 6 to remove the redundant microcode related fields in the CPU_MP_DATA structure. V1 history: 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.
