ArmEnableVFP could crash on an out-of-order CPU. Adding an instruction barrier after writing to CPACR cures the problem.

Some ARM Platform components (ie: PrePei) use this constructor name to
initialize the timers (at this time there is no PE loader to call the
library constructors) when PI/UEFI is started to initialize the
PerformanceLib.

The initrd was loaded at the top of the UEFI System Memory. By consequence, if the system memory
was reduced by the Linux command line then the initrd was not part of the system memory.

Change __aeabi_uread4 from:
ldrb r2, [r0, #1]
ldrb r1, [r0]
(...)
to:
ldrb r1, [r0]
ldrb r2, [r0, #1]
(...)
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.

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.

The previous version was only checking if the Remaining Device Path node
was a MemMap DevicePath node.
This fix also checks if the Root DevicePath node is a MemMap DevicePath node.

Some coherencies issues were existing in the former version of DmaLib.
These issues could have for consequences to not make the MdeModulePkg/Bus/Usb

This library is used to display the loaded address of the 'Sec' at the early
stage of the boot process. The debug command line generated by PeCoffExtraActionLib
can be used for Source Level Debugging at the early stage of the UEFI boot process.

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.
