This library could be used before the UEFI phases to expose the CPU state
when an unexpected exception interrupt the firmware.

In case a DebugAgent library is supported for a specific debugger, we would
expect the exception be caught by DebugAgentLib.
The DebugAgentBaseLib exposes the cause of the exception to the user in the
Serial Terminal.

license is either BSD or GPL). The BSD license is the license that fits to the
Tianocore contribution requirements.
The use of libfdt into Tianocore has been authorised by David Gibson the
author of libfdt and its current maintainer Jon Loeliger (email thread on 7th

EFI_MEMORY_UC is mapped to Strongly Ordered memory while EFI_MEMORY_WC is
mapped to Uncached Normal/System memory.
This change improve performance while accessing uncached regions in the
System Memory.

Because the D&I caches were clean before to be disabled, the cache
lines might have got dirty during the cache maintenance operations.
This fix disables D&I caches before to clean them. The performance
drops should be minimised as invalidating the I cache is only a
couple of instruction.

If the first call of gBS->GetMemoryMap() succeeded (could happen if the Memory Map
has changed between the two gBS->GetMemoryMap() calls) in the loop block then
gBS->ExitBootServices() was never called.

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.
