This change is a workaround to handle correctly __aeabi_uread4 on ARM
Versatile Express RTSM.
It should not have any major consequence on the other ARM platforms.

This change does not make possible to disable Trustzone from the firmware.

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
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.

There are two variants of the Linux Loader EFI application:
- the ATAG version 'LinuxAtagLoader.inf': expect to start an ATAG 'zImage'
in the same directory as the EFI application
- the FDT version 'LinuxFdtLoader.inf': load the FDT blob 'platform.dtb'
and the FDT 'zImage' from the same directory as the EFI application.
When these applications are started without any argument, a menu appears
to the user to create/update a boot entry.

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.

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).

Previously the CPU driver had a dependency on the GIC driver.
But by design is should be the opposite. The CPU driver installs the
CPU protocol that exposes the exception registration function.
And then, the interrupt controller registers its IRQ handler through
this interface.

The previous version was using the string representation of the Device Path.
This new version takes as paramater the binary representation of the Device Path
It also tries to detect which kind of device support it refers by using the remaining

Formerly, each platform was responsible to declare the location of its UEFI memory
region (used by PEI and DXE Foundations).
The ArmPlatformLib was also declaring every region of its partitionned system memory
with a System Resource HOB.
In this new model, the MemoryInit expects the system memory to be declared with the
PCDs gArmTokenSpaceGuid.PcdSystemMemoryBase/Size.
These PCDs declare the largest continuous DRAM region. Additional regions can be
declared with the ArmPLatformLib function ArmPlatformGetAdditionalSystemMemory().
Now, it is the PEIM that partitions the system memory for every platform. It installs
a region of the size PcdSystemMemoryUefiRegionSize (default 128MB) for the PEI permanent
memory at the top of the DRAM region.
And a region of gArmPlatformTokenSpaceGuid.PcdSystemMemoryFixRegionSize (default 128MB)
is declared at the base of the system memory. This region is used for the allocation that
requires fixed address or have some constraints on their locations.
