The GICD_IGROUPR0 is banked for each connected processor. It means the
Non-Secure bits for the PPIs (Private Peripheral Interrupts) must be
configured for every processor.

This NULL implementation should not affect the existing code flow and
avoid the builds to be broken by a missing dependency.
In a longer term, an implementation of CpuExceptionHandlerLib should
be provided for ARM architecture.

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

CFI Flash differentiates DeviceBaseAddress with BlockAddress in
its protocol. The DeviceBaseAddress was not considered in the
previous version of this driver.
This version also fixes some bugs in the implementation of the
CFI protocol.
This new version also uses the Boot Mode Hob to reinitialized the
FVB when Boot Mode is equal to BOOT_WITH_DEFAULT_SETTINGS.

The enter_monitor_world() function was trashing r0/r1/r2 registers and then
was returning back to 'C'. The compiler might have used these registers in the C code.
These new design prevents register corruptions.

The stacks must be 32-bit aligned (which is not the case of 0xFFFFFFFF).
This change ensures the stacks are setup properperly in case the system
memory is available at 0xFFFFFFFF.

This library interface is not related to adding extra action to debug support.

Because GET_CORE_POS(MpId) returns 0x0 for the primary core, the
stack position must be defined by the top of the stack. It means
stack_size must be added to the stack base.

The Variable PEI and RuntimeDxe drivers were using the attribute 'HeaderLength' of
EFI_FIRMWARE_VOLUME_HEADER without checking if a Firmware Volume Header was existing at
the base address.
In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength'
is a non valid value that can lead to a non valid physical address when accessing produces an
access error.

Some compilers uses VFP for some 64bit operation. If the VFP coprocessor is not enabled at
this stage the processor raises an undefined exception.
To prevent this case, the VFP enabling has been moved at the beginning of the platform
initialization phase.

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

This change does not make possible to disable Trustzone from the firmware.
The firmware has to be built for Trustzone support enabled or disabled.
The memory page table are now defined as 'Normal Memory' in any case.

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.

In the previous version, every cores had the same stack size.
To avoid to waste memory with secondary core stacks, the primary core stack
size is now different from the secondary cores stack size.
These are the Stack PCDs and their default values:
gArmPlatformTokenSpaceGuid.PcdCPUCoresSecStackBase|0
gArmPlatformTokenSpaceGuid.PcdCPUCoreSecPrimaryStackSize|0x10000
gArmPlatformTokenSpaceGuid.PcdCPUCoreSecSecondaryStackSize|0x1000
gArmPlatformTokenSpaceGuid.PcdCPUCoresSecMonStackBase|0
gArmPlatformTokenSpaceGuid.PcdCPUCoreSecMonStackSize|0x1000

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.
