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).
ArmPlatformPkg: Enable DebugAgentLib in Sec and PrePeiCore
ArmPlatformPkg: Fix line endings in some source files
Use CR+LF line endings as defined by the EDK2 coding convention

This constructor should be explicitely called by the Sec or PrePi phase
to initialize the OMAP353x timers.
This function is a copy of the Timer initialization function in BeagleBoardPkg/Sec.

BeagleBoardPkg: Switch to ArmPLatformPkg/Bds
The ArmPlatformPkg/Bds is able to boot Linux. Set the default boot device
for the BeagleBoardc to the SD card.

If a FDT blob is passed to the kernel it is required we can load it.
If we fail to load the binary then we must abort the Linux booting
process.
ArmPkg/CpuDxe: Ensure the reset vector passed to the CP15 VBAR register is aligned on the right boundary

The $(BUILD_TARGETS) macro was used to make the difference between DEBUG and
RELEASE builds. The $(TARGET) macro should be used instead.

When using ArmPlatformPkg/PrePeiCore or ArmPlatformPkg/PrePi, the global variable during
the XIP phase are stored on the top of the stack.
Global variables are defined by their PCD offset from the top of this stack.
For example, the HobListPtr is defined at the offset PcdHobListPtrGlobalOffset.

The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).
ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h
- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace

This module is enabled for ArmRealViewEb and ArmvExpress builds
when the macro EDK2_SKIP_PEICORE is passed to the build system.
The PrePi module can be used when the DRAM has already been initialized
by the SEC phase/1st stage boot loader and no call to external PEIM is
required.

Feature PCDs cannot be used in assembly files.
The PcdStandalone PCD is needed in one of the assembly file of the
ArmPlatformPkg/PrePi module.

In the aim to reuse the Platform Pei features in a PrePi module (use to
skip the PEI Core), this module has been divided into two files:
- PlatformPeiLib: declare the platform HOBs
- PlatformPeim: PEIM wrapper for the library

In the aim to reuse the memory init features in a PrePi module (use to
skip the PEI Core), this module has been divided into two files:
- MemoryInitPeiLib: declare the memory HOBs
- MemoryIniPeim: PEIM warpper for the library
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11950 6f19259b-4bc3-4df7-8a09-765794883524
This module should handle the Pre PI phase before the DXE core is
executed when there is no PEI Core support.
It declares the required information needed by the DXE core through HOBs.

This function only create the HOB Handoff Info Table structure in memory.
In opposition to CreateHobList() that creates the structure and starts to
populate it with few HOBs.

This interface allows to use different mechanism to store the HobList Pointer.
EmbeddedPkg/PrePiHobListPointerLib: Implementation of PrePiHobListPointerLib using PCD
This library uses a PCD to store the location of the HobList Pointer.

The PrePiLib should really be used for the PEI phase (not the SEC phase).
It is the DXE core that take the tick for the end of the PEI phase.
The Platform PrePi module should be responsible to take the tick when it
starts for the PEI phase.
