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 Secure and Normal World
Having a similar setup reduces the error during the MPCore stack setup.
The stack setup is described on this wikipage:

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.

library invocation
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.

ArmPlatformLib
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.

gArmTokenSpaceGuid.PcdTrustzoneSupport
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.
Except for RTSM Device Memory which as to be Secure Device Memory due
to a RTSM bug.

Every CPUs have their own initialization requirements.
This library allows to allows to abstract these initialization requirements
into the ARM Platform common components.

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

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.

ArmPlatformSecExtraAction()
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).

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.
