The SMM memory attribute table concept is similar to UEFI memory attribute table. The new file MdeModulePkg/Core/PiSmmCore/MemoryAttributesTable.c and the new code in MdeModulePkg/Core/PiSmmCore/Page.c are based on the algorithms and implementation from MdeModulePkg/Core/Dxe/Misc/MemoryAttributesTable.c and MdeModulePkg/Core/Dxe/Mem/Page.c. These new components are based on the Memory Attributes Table feature from the UEFI Specification and the existing DXE Core implementation that supports that feature. This SMM MemoryAttributes table is produced at SmmEndOfDxe event. So that the consumer (PiSmmCpu) may consult this table to set memory attribute in page table. This patch also installs LoadedImage protocol to SMM protocol database, so that the SMM image info can be got easily to construct the PiSmmMemoryAttributes table.
