StandaloneMmPkg: Simplify returning event complete values
Communication with Stmm can be via SPM using MM or FF-A.
However, some return values differ between these
communication models.
This patch adds helper functions to covert the return
values based on the communication model.
It also fixes an issue when using the SPM using MM model,
wherein an error code value of -7 was being returned when
an unknown error occurred. The -7 value is not defined in
SPM using MM. Therefore, return an UNSUPPORTED code instead.

StandaloneMmPkg: Introduce PI_MM_CPU_DRIVER_EP protocol.
This patch introduces a PI_MM_CPU_DRIVER_EP protocol to handle
Mmcommunication request based on the CPU driver.
Previously the CPU driver entry point was retrieved using the
gEfiArmTfCpuDriverEntryPoint HOB.
However, this practice is incorrect as StandaloneMM must be a HOB
consumer and not a HOB producer.
Therefore, remove the CPU entry HOB gEfiArmTfCpuDriverEntryPoint,
and replace it with the CPU driver entry protocol
EDKII_PI_MM_CPU_DRIVER_EP_PROTOCOL.
The EDKII_PI_MM_CPU_DRIVER_EP_PROTOCOL installed in
StandaloneMmCpuInitialize() will be used by the code in
Arm/StandaloneMmCoreEntryPoint.
This protocol is used like below:
+=====+
|StandaloneMmCore|
+=====+

CEntryPoint()
===================

ProcessModuleEntryPointList()

StandaloneMm/Library: Remove Hob creation on Arm CoreHob Library
By using transfer list passed by TF-A,
StandaloneMmCore is no more producer of HOBs, But it is consumer.
So, the Arm-specific implementation of StandaloneMmCoreHobLib
is no longer needed.
This change removes the Arm-specific HOB creation code and

ArmPkg/Library: Update StandaloneMmuLib with FF-A v1.2 with page granulirty
The StandaloneMm implementation for Arm sets up the stack in
the early startup code using the data section reserved in the
assembly code.
When TF-A loads the StandaloneMM binary in the DRAM it maps
the entire StandaloneMM memory region as Read Only.
Therefore, the initial startup assembly code updates the mem
permissions of the stack region to Read Write.
However, when the StandaloneMmCore is loaded the function
UpdateMmFoundationPeCoffPermissions() starts applying the
memory permissions based on the PE COFF sections as below:
A. If the section is not executable, it first removes the
executable permission of the section by calling TextUpdate().
TextUpdate() is the StandaloneMM MMU library function
ArmSetMemoryRegionNoExec().
B. It then checks if the section is writable, and if it is
it calls ReadWriteUpdater(), which invokes the StandaloneMM
MMU library function ArmClearMemoryRegionReadOnly() to make
the section writable.
However, this results in the stack being made read-only
between A and B. To understand this please see the following
flow.
1. TF-A sets the entire StandaloneMM region as Read Only.
2. The stack is reserved in the data section by the early
assembly entry point code.
+--------------------+ <--- Start of Data Section
| |
| Data Section |
| |
| +----------------+ | <--- Stack region
| | Stack | |
| +----------------+ |
| |
+--------------------+
3. The StanaloneMM early entry point code updates the
attributes of the stack to Read Write.
4. When UpdateMmFoundationPeCoffPermissions() sets the
permission of the data section to remove the Execute
attribute, it calls ArmSetMemoryRegionNoExec().
5. The ArmSetMemoryRegionNoExec() implementation gets the
attributes of the first granule which is at the start
of the data section, then clears the execute permission
and applies the attribute for the entire data section.
6. Since TF-A has mapped the entire section as read only
the first granule of the data section is read only and
therefore the stack region attributes are changed to
Read Only no execute.
7. Since the stack is read only after point A any updates
to the stack result in an exception.
To resolve this issue with update the library with FF-A v1.2,
get/set memory permission per page unit.

To support the service other than Mmcommunication service,
StandaloneMm should use FF-A v1.2 or later [0].
For this, StandaloneMm needs to change:
1. apply FF-A boot protocol
- FF-A uses its own boot protocol and it can deliver phit hob.
So, StandaloneMm should understand FF-A boot protocol and
get phit hob from it to initialize.
2. Use DIRECT_REQ2 / DIRECT_RESP2
- To support the other service via FF-A protocol
than MmCommunication,
StandaloneMm should use DIRECT_REQ2 / DIRECT_RESP2.
In case of service provided with MmCommunication protocol,
register x2/x3 value is set as gEfiMmCommunication2ProtocolGuid and
register x4 value is set with MmCommunication Buffer
(ServiceTypeMmCommunication).
In case of service with each speicifiation via FF-A,
register x2/x3 value is set as each service guid
and StandaloneMmCoreEntryPoint genreates Mm communication header
with passed arguments to dispatch this service
provided by StandaloneMm.
i.e) Tpm service, Firmware update service and etc.

StandaloneMmCore: Change log level when mCommunicationBuffer is NULL
On Arm all requests are handled as Asynchronous events by the Root
MMI handler.
Since the communication data is conveyed using either the NS shared
buffer or the Secure shared buffer, the Arm implementation does not
setup the mCommunicationBuffer. Therefore, the mCommunicationBuffer
being NULL is not an error case.
Moreover, the existing code switches to Asynchronous event processing
when the mCommunicationBuffer is NULL, which means that the log is an
info log rather than an error.
Therefore, change the log level from ERROR to INFO when the
mCommunicationBuffer is NULL.

StandaloneMmPkg: Apply embedded stack in StandaloneMmEntryPoint
There are 2 communication interfaces between the SPMC and StandaloneMM
1. SpmMM
2. FF-A
When SpmMM is enabled, TF-A acts as the SPMC at EL3 and the stack is setup
by TF-A for use by StandaloneMm. However, when FF-A is enabled, the SPMC
does not setup the stack for StandaloneMm and it is expected that the
StandaloneMm code will setup its own stack.
Therefore, reserve an area in the data region for use as the stack for
StandaloneMM. This stack will be used in both the scenarios described
above, i.e. when either SpmMM or FF-A is enabled.
Although the stack is reserved from the data section which is expected
to be Read-Write enabled, when TF-A maps the StandaloneMM binary into
the DRAM it configures the entire StandaloneMM memory as Read-Only.
Therefore, before the stack can be utilised, the PE Coff sections
need to be scanned to change the the stack region from Read-Only to
Read-Write.

StandaloneMmPkg: Move sanity check for comm buffer to entrypoint
Arm has three types of communication buffer
- Non secure communication buffer: shared buffer with NS partition
- Secure communication buffer: shared buffer with Secure partition
- Internal Misc service buffer: For misc service
i.e. for services that do not use MmCommunication protocol,
a buffer is created and populated internally.
Since, internal Misc service buffer is allocated dynamically in
StandaloneMm there is no additional check required for the Misc
service buffer.
This patch move sanity check of communication buffer from
StandaloneMmCpu Driver to StandaloneMmEntryPoint.

StandaloneMmPkg: remove per-cpu feature on StandaloneMm
StandaloneMm in Arm is UP-migratable which means StandaloneMm
cannot run concurrently.
Therefore, remove per-cpu feature in StandaloneMm.

StandaloneMmPkg: introduce StandaloneMmExtractGuidedSectionLib
The default ExtractGuidedSectionLib used by Standalone MM is the
implementation in EmbeddedPkg. However, the ExtractGuidedSectionLib
implementation in EmbeddedPkg builds HOBs to save the extract handler
information.
Since StandaloneMm is consumer of HOB, not a HOB producer, introduce
a StandaloneMmExtraGuidedSectionLib implementation that saves the
extract handler information in the ConfigurationTable.
This StandaloneMmExtraGuidedSectionLib can be used by MM_STANDALONE
and MM_CORE_STANDALONE modules.
