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.

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.

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.

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).

A dummy padding was added before the Reset Vectors to force the alignment on a
32 bytes boundary in XIP code.
The correct fix is to define the alignment in the FDF file.

If none of the Simple Text Input/Output Protocol implementations were started
before starting BDS then an exception error occured.
This fix forces to connect all the drivers if no SimpleText IO protocols are
found.

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.

This function is responsible to handle all the specific platform code that must
be run in secure world to initialize some controllers.
ArmPlatformPkg/Sec: Move the L2x0 initialization to ArmPlatformLib
The L2x0 controller must be initialized in secure world. Move its initialization
into the ArmPlatformInitialize() of the Cortex A9x4 Core Tile PlatformLib.
