Like the ArmVirtPkg platforms up until SVN r17713, the ArmPlatformPkg
platforms built with the Intel BDS fail to signal the end-of-DXE event
'gEfiEndOfDxeEventGroupGuid' when entering the BDS phase, which results
in some loss of functionality, i.e., variable reclaim in the VariableDxe
drivers, and the splitting of the memory regions that is part of the recently
added UEFI 2.5 properties table feature.
As discussed on the edk2-devel mailing list here:
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109
it is up to the platform BDS to signal that event, since there may be
platform specific ordering constraints with respect to the signalling
of the event that are difficult to honor at the generic level.
So add the SignalEvent () call to PlatformBdsInit () of ArmPlatformPkg's
PlatformBdsLib implementation for the Intel BDS.

This change allows to change the top of the System Memory that
was hardcoded by:
FixedPcdGet64 (PcdSystemMemoryBase) + FixedPcdGet64 (PcdSystemMemorySize)
It allows to add support when the Trusted Firmware reserves the
top of the System Memory as Trusted. The size of this region
might not be known in advance.
Note: The reason why the start of the System Memory has not been
made dynamic is because the early code calculates where to place
the stack from the top of the System Memory.
So there is no need to make the start of the System Memory a
dynamic value at the early stage of the boot phase.

Instead of keeping this function empty for most platforms, the function has been
removed. This feature can easily fit in any other ArmPlatformLib function.

By copying these templates, it should make easier to port EDK2 to new ARM
Platforms.
- ArmPlatformPkg.(dsc|fdf): For EDK2 firmwares which support the full boot
story from cold boot to OS loading
- ArmPlatformPkg-2ndstage.(dsc|fdf): For EDK2 as a second stage boot loader
(either started after a proprietary ROM firmware or x-loader)

This library hides where the 'XIP' Global Variable are located in the memory.
It is expected the Sec/PrePi modules define the Global Variable area through
the GlobalVariable HOB.
The ArmPlatformGlobalVariableLib library allows access to global variables by
their offsets in this region.

The denomination 'Normal' was used to make reference to the 'Normal'
or 'Non Secure' or 'Non Trusted' world.
To avoid confusion, this prefix has been removed from PCDs to define
the normal world.
The PCDs explicitely related to the Secure/Trusted World continue to
have the 'Sec' prefix.

On MpCore system, the primary core can now be any core of the system.
To identify the primary core, you can use 'gArmTokenSpaceGuid.PcdArmPrimaryCoreMask'
and 'gArmTokenSpaceGuid.PcdArmPrimaryCore'.
These PCDs by default use the ClusterId and CoreId to identify the core. And the
primary core is defined as the ClusetrId=0 and CoreId=0.
The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId),
GET_CORE_POS(MpId), PRIMARY_CORE_ID.

This library is the interface for the ARM Generic Interrupt Controller
Architecture Specification.
ARM Platform can use any GIC controller (not necessary PL390 GIC).

Before the PI Global Pointer Offsets were refered to the top of the Global Pointer region (negative offset).
After this commit the Global Pointer Offset are relative to the base of the Global Pointer region.

In the PrePi module, the global variables are located at the top of the stack.
At the opposite of the PeiCore where the global variables are located in the
middle of the stack. The top stack region is reserved for Temporary Memory.

In the previous implementation, if the MicroSecondDelay or NanoSecondDelay
were called while a delay function was already running, the timer HW controller
was reinitialized with the new settings and it was discarding the settings
of the first called delay function.

The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot
from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware
engineer has to copy the Normale World image into the DRAM to enable his/her firmware).
By coping the firmware into DRAM in the non standalone version it is much faster than reflashing
the NOR Flash after each build.
ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world.
The platform firmware can run extra actions at this stage.
The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for
the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib).
ArmPlatformPkg: Enable DebugAgentLib in Sec and PrePeiCore
ArmPlatformPkg: Fix line endings in some source files
Use CR+LF line endings as defined by the EDK2 coding convention

When using ArmPlatformPkg/PrePeiCore or ArmPlatformPkg/PrePi, the global variable during
the XIP phase are stored on the top of the stack.
Global variables are defined by their PCD offset from the top of this stack.
For example, the HobListPtr is defined at the offset PcdHobListPtrGlobalOffset.

The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).
ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h
- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace

The size of this memory is controlled by a PCD. The Global Variable in this regsion are defined by their offset.
This memory region can be use to store the PEI Services Table Pointer.
Update the PeiServicesTablePointerLib to use this region instead of PcdPeiServicePtrAddr.
