The patch attached is to fix the issue that LMFA feature is failed on OVMF. The root cause is that OVMF platform reserved 128k top memory range for EMU variable range before PEI memory range re-locate to specified memory range, which is quite different from real platform. The original implementation has an assumption that AllocatePage will NOT be invoked until PEI memory range is re-located to preassigned memory range, , which is TRUE in most real platform, but FALSE on OVMF platform. So This patch is to enhanced the memory resource HOB re-organization algorithm to eliminate the assumption.

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.
