RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937 EdkiiMemoryAcceptProtocol is defined in MdePkg, the method AcceptMemory() can be called when memory needs to be accepted. EdkiiMemoryAcceptProtocol can be installed by architecture-specific drivers such as TdxDxe. This allows different isolation architectures to realize their own low-level methods to accept memory.
