主题: [edk2-devel] [edk2-platforms][PATCH v1 1/1]
MinPlatformPkg/Acpi/AcpiSmm: Add Standalone MM support
From: Michael Kubacki <michael.kuba...@microsoft.com>
Adds a new module called AcpiStandaloneMm that serves the same role
as AcpiSmm but in a Standalone MM environment.
This change follows a similar pattern to other changes that have
added Standalone MM support to a SMM module. The SMM INF name and
file path remain unaltered to allow backward compatibility and much
of the code is shared between the driver instances with unique entry
points for each respective module type.
