1) MdeModulePkg/DxeCore: Install UEFI mem attrib table at EndOfDxe. So that the SMM can consume it to set page protection for the UEFI runtime page with EFI_MEMORY_RO attribute. 2) MdeModulePkg/DxeCore: Not update RtCode in MemAttrTable after EndOfDxe We want to provide precise info in MemAttribTable to both OS and SMM, and SMM only gets the info at EndOfDxe. So we do not update RtCode entry in EndOfDxe. The impact is that if 3rd part OPROM is runtime, it cannot be executed at UEFI runtime phase. Currently, we do not see compatibility issue, because the only runtime OPROM we found before in UNDI, and UEFI OS will not use UNDI interface in OS.
