Since the System Memory initialization has been moved inside ArmPlatformSecLib
on some platforms, the use of this library could crash if the firmware engineer
forgot to initialize the DRAM.
This library 'patches' the DRAM to add an infinite loop.

The function only used in Secure Firmware used to be mixed with
the Non-Secure/Normal functions in ArmPlatformLib.
When the Secure Firmware was not required for some platforms (eg:
BeagleBoard), these functions were empty functions.
This new interface has been created to clean the ArmPlatformLib
interface between the SEC and PEI phases.

- ArmPlatformNormalInitialize() has been renamed into ArmPlatformInitialize()
- Make the function be called at the early stage of the PEI phase as some
platforms require their interconnects or clocks to be initialize before any
access to Timers or UARTs.

The GICD_IGROUPR0 is banked for each connected processor. It means the

Because this driver can be used for different purposes (Terminal, Debug port, communication),
its initialization function has been extended to accept additional settings.

Memory map remapping is a platform specific feature only enabled by some platforms.
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.

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

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

- 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.

The SP804 drivers must not consider the presence of the SP810 System Controller
on the platform. The SP810 was used to enable the SP804 Dual Timers on ArmVExpress.
It is the role of the Platform specific driver to enable to the SP804 dual timers
if required.
The former SP810 initialization code has moved to ArmPlatformLib for ArmRealViewEb
and ArmVersatileExpress.

Formerly, it was only possible to use section size granularity for the
translation table regions.
This change allows to define initial translation table regions with
4K-byte granularty (page size granularity).
