For instance, in case of CpuHotPlug boot path the platform has already been
initialized. The CPU core should not execute any of the platform initialization
in this case.

Since the System Memory initialization has been moved inside ArmPlatformSecLib
on some platforms, the use of this library could crash if the firmware engineer
forgot to initialize the DRAM.
This library 'patches' the DRAM to add an infinite loop.

The function only used in Secure Firmware used to be mixed with
the Non-Secure/Normal functions in ArmPlatformLib.
When the Secure Firmware was not required for some platforms (eg:
BeagleBoard), these functions were empty functions.
This new interface has been created to clean the ArmPlatformLib
interface between the SEC and PEI phases.

Previsouly the synchronization of MpCore was using the SGI (Software
Generated Interrupt) to synchronize MpCore during the early boot.
This commit replaced this mechanism by the more appropriate SEV/WFE
instructions (Send/Wait Event instructions).
That also eases the port to a new cpu/platform.

This function was introduced in some drivers to check if the ARM controller
was present in the memory map.
It was using a 8 bit access to get the value from the Identification registers.
These accesses could generate access error on some buses. Instead of replacing
the 8bit access by a 32bit access, these fcuntions have been removed because
they are only useful when the boot firmware is ported on a new platform.

- ArmPlatformNormalInitialize() has been renamed into ArmPlatformInitialize()
- Make the function be called at the early stage of the PEI phase as some
platforms require their interconnects or clocks to be initialize before any
access to Timers or UARTs.

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

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.
