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.

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.

jyao1 ab780ebf90 Change BufferSize from UINTN * to UINTN to eliminate pointer to pointer in SmmCore for security consideration.

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.

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.
