*	PrmPkg: Add PrmConfig protocol interface	Michael Kubacki	2022-04-05	1	-0/+32
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812 The PRM Configuration protocol is used by PRM module configuration libraries to describe their resources so that a generic PRM Configuration DXE driver can prepare those resources for OS runtime. Therefore, multiple instances are expected in the system per boot with approximately one instance per PRM module. All PRM Configuration Protocol instances must be installed prior to end of DXE.

*	PrmPkg: Add package and include headers	Michael Kubacki	2022-04-05	10	-0/+577
	REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812 Adds a new package to maintain Platform Runtime Mechanism (PRM) support. This package is intended to include generic code that provides a common infrastructure to support PRM in firmware and a collection of sample PRM modules that demonstrate how to use the interfaces and other package resources to author a PRM module. The following initial headers are included in this commit: * Prm.h - Includes common content for PRM with no dependencies on other PRM header files. * PrmContextBuffer.h - Includes definitions for PRM context buffers. Context buffers are standardized structures that point to various resources available to a PRM handler during its execution. * PrmDataBuffer.h - Includes definitions for PRM data buffers. Within the context of PRM, these data buffers are composed of a generic header followed by a variable length blob of arbitrary data. * PrmExportDescriptor.h - Includes definitions for creating PRM export descriptors. A PRM export descriptor is a structure referenced in the export table of PRM module that contains PRM-specific metadata about the module. * PrmMmio.h - Includes definitions for describing MMIO ranges uses by PRM modules. * PrmModule.h - Includes definitions commonly used by PRM module authors. This file is provided to serve as a convenient include for PRM module authors. * PrmOsServices.h - Includes content specific to PRM OS services. OS Services will not planned to be present in the final version of PRM. The OS Services have been reduced to a simple debug print function. So this is currently planned to be a temporary file to support debugging during PRM development. Note: Modules built for the UEFI environment can be built by Visual Studio and non-Visual Studio toolchains. However, PRM modules are currently only supported on Visual Studio toolchain due to usage of export tables.
