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.

This library that uses the DebugAgentLib interface prints the loaded addresses
of the SEC and PEI_CORE module using PeCoffExtraActionLib.
Note: Because there is no PE loader for these XIP modules, PeCoffExtraActionLib is not invoked.
This library scans the firmware volume to find these modules and calculate their fixup loaded
addresses used to load their symbols in the debugger.

- Give an overview of the different possible boot phases on ARM platforms (using
EDK2 for the full boot story or limiting its use to the last boot sequence)
- Show which functions to implement in ArmPlatformLib following the the boot phases

In the former memory model, the UEFI firmware was expected to be located
at the top of the system memory. Stacks & Pi memory regions were set below
the firmware.
On some platform, the UEFI firmware could be shadowed by the ROM firmware
(case of the BeagleBoard) and in some cases the firmware is copied at the
beginning of the system memory.
With this new memory model, stack and Pi/DXE memory regions are set at the
top of the system memory wherever the UEFI firmware is located in the memory
map.
Because DXE core does not support shadowed firmwares, the system memory covered
by the UEFI firmware is marked as 'Non Present' to avoid to be overlapped by
DXE allocations.

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

The $(BUILD_TARGETS) macro was used to make the difference between DEBUG and
RELEASE builds. The $(TARGET) macro should be used instead.

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

This module is enabled for ArmRealViewEb and ArmvExpress builds
when the macro EDK2_SKIP_PEICORE is passed to the build system.
The PrePi module can be used when the DRAM has already been initialized
by the SEC phase/1st stage boot loader and no call to external PEIM is
required.

Feature PCDs cannot be used in assembly files.
The PcdStandalone PCD is needed in one of the assembly file of the
ArmPlatformPkg/PrePi module.

In the aim to reuse the Platform Pei features in a PrePi module (use to
skip the PEI Core), this module has been divided into two files:
- PlatformPeiLib: declare the platform HOBs
- PlatformPeim: PEIM wrapper for the library

In the aim to reuse the memory init features in a PrePi module (use to
skip the PEI Core), this module has been divided into two files:
- MemoryInitPeiLib: declare the memory HOBs
- MemoryIniPeim: PEIM warpper for the library

This module should handle the Pre PI phase before the DXE core is
executed when there is no PEI Core support.
It declares the required information needed by the DXE core through HOBs.

There were some assumptions that some PCDs and protocols were defined.
Check if these requirements are defined; either print a debug message
to inform the user or skip the statements that require these PCDs or protocol.

- uncaught returned error

The code specific to the secure intialization has been moved into a
separate file that is not linked with the Normal world version of the
library.

With this change, we now have these following PCDs values to define the
location of the Secure and Normal firmwares:
- gArmTokenSpaceGuid.PcdSecureFd(BaseAddress|Size)
- gArmTokenSpaceGuid.PcdSecureFv(BaseAddress|Size)
- gArmTokenSpaceGuid.PcdNormalFd(BaseAddress|Size)
- gArmTokenSpaceGuid.PcdNormalFv(BaseAddress|Size)

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.
