[PATCH edk2-platforms 0/3] Platform/ARM/SgiPkg: Enable StandaloneMm on Sgi platforms

[Sughosh Ganu]

The following patches enable building of StandaloneMm image on Sgi
platforms.

The first patch adds build infra for StandaloneMm image. The second
patch of the series adds memory buffer required for communication
between the non-secure world with StandaloneMm image using MM
Communicate. The third patch of the series enables MmCommunication
module on the platform for it subsequent use by features like
Secure-Boot and Error Injection and Handling for RAS.

  Platform/ARM/SgiPkg: Build infrastructure for StandaloneMm image
  Platform/ARM/SgiPkg: Setup memory buffers for MmCommunicate
  Platform/ARM/SgiPkg: Enable MmCommunication module on the platform

[PATCH edk2-platforms 3/3] Platform/ARM/SgiPkg: Enable MmCommunication module on the platform

[Sughosh Ganu]

The ArmMmCommunication module is used for communication between
non-secure and secure world using Arm's Management Mode
Specification. Enable this module on Sgi platforms. This would be used
subsequently by the RAS and SecureBoot features, support for which
is to be added on the platform..
