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.
