rsun3 96756716c0 when SMM Communication Protocol.Communicate() is called from within SMM, SMRAM is accessible so it is not necessary to check the SMRAM open/lock state via SMM ACCESS Protocol.

mdkinney fa542a1e77 1) Change location of DEBUG() macro that prints the name of the FFS file being evaluated by the DXE Dispatcher to eliminate a duplicate print. 
2) Change location of DEBUG() macro that prints the name of the FFS file being evaluated by the SMM Dispatcher to eliminate a duplicate print.
3) Remove all references and processing of SOR from the PiSmmCore.  Treat use of SOR in the dependency expression of an SMM Driver as an invalid depex opcode.
4) Remove all references for an SMM Driver being in the "Untrusted" state from the PiSmmCore.

mdkinney 6a55eea3eb Update PEI/DXE/SMM dispatchers to include DEBUG ((DEBUG_DISPATCH, )) macros to log the evaluation of all dependency expressions. 
This logging can be enabled by setting the DEBUG_DISPATCH bit(0x80) of the PCD gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel.

rsun3 0a6c090521 Complement fix for revision #10998 (Remove PI SMM IPL's dependency on CPU AP).

rsun3 07d9dc83f4 Remove PI SMM IPL's dependency on CPU AP so that PI SMM IPL can be dispatched before the CPU AP is installed. 
If PI SMM IPL will be dispatched before the CPU AP is installed for a platform, the platform developer is expected to set cache-ability of SMRAM to WB earlier to improve performance of SMM initialization.

jgong5 40e8cca588 Fix the SMRAM caching range base and size. The original code uses the biggest SMRAM range base and size to set the cache attribute by gDS->SetMemorySpaceAttributes(). This is not correct because the platform code might split the TSEG into several ranges. The fix searches and joins all the adjacent ranges to the biggest SMRAM range into a cacheable range so that TSEG can be cached as a whole.

hhuan13 1fc17d768f Remove Size==0 branch in SmmAllocatePool() 
The background is :

The SmmMemoryAllocationLib of one of the instance of MemoryAllocation library class. As in MdePkg comment for AllocatePool() : “If AllocationSize is 0, then a valid buffer of 0 size is returned.”,the SMM library implements AllocatePool by SMST service SmmAllocatePool which does NOT support the zero size.

jyao1 06b07ce37c Change the minimal SMM core size from 1MB to 256KB-4K. 
Some platforms only enable 1MB, after reserve 1 page for SMM S3. There is at most 1MB-4KB for SMM core.

hhuan13 3c5963cf29 Update PiSmmCore: 
1. Update PiSmmIpl.c DoCommunicate() to prevent exception in case call SmiManage directly if SMRAM is closed or locked. That case causes exception.
2. Update PiSmmCore.c SmmEntryPoint(). It is not required to save/restore InSmm. Because SMM is non-reentrant.

jgong5 34f60e4d77 Add EfiCpuArchProtocol dependency for PiSmmIpl module. The reason to add this is PiSmmIpl will call gDS->SetMemorySpaceAttributes() which will locate CPU Arch Protocol to set MTRRs. Without this dependency, the locate might fail and MTRRs are never set in this case.
